- Visual outcomes after implantation of a novel refractive toric multifocal intraocular lens(2014) SHIMODA, Talita; SHIMODA, Gilberto; HIDA, Wilson Takashi; NAKANO, Celso Takashi; MOTTA, Antonio Francisco; GUIMARAEES, Aline Silva; TZELIKIS, Patrick Frensel M.Purpose: To assess the postoperative outcomes of a novel toric multifocal intraocular lens (IOL) in patients with cataract and corneal astigmatism. Methods: This prospective nonrandomized study included patients with cataract, corneal astigmatism, and a motivation for spectacle independence. In all patients, a Rayner M-flex (R) T toric IOL was implanted in the capsular bag. Three months after surgery, the distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity were evaluated. A patient satisfaction and visual phenomena questionnaire was administered to all patients. Results: Thirty-four eyes of 18 patients were included in this study. Three months after surgery, the mean corrected distance visual acuity (logMAR) was 0.00 +/- 0.08 at 6 m, 0.20 +/- 0.09 at 70 cm, and 0.08 +/- 0.11 at 40 cm. Uncorrected distance vision acuity was 20/40 or better in 100% eyes. The preoperative mean refractive cylinder (RC) was -2.19 (SD: +/- 0.53). After a 3-month follow-up, the average RC was -0.44 D (SD: +/- 0.27; p<0.001). Contrast sensitivity levels were high. At the last follow-up, 87.5% patients were spectacle-independent for near, intermediate, and distance vision, and approximately 44% patients reported halos and glare. Conclusion: Toric multifocal IOL implantation in patients with cataract and corneal astigmatism using the Rayner M-flex (R) T toric IOL was a simple, safe, and accurate option. This technology provides surgeons with a feasible option for meeting patient expectations of an enhanced lifestyle resulting from decreased spectacle dependence.
- Elaboração e validação do questionário de satisfação dos pacientes pseudofácicos em português(2013) HIDA, Wilson Takashi; NAKANO, Celso Takashi; YAMANE, Iris; MOTTA, Antonio Francisco Pimenta; TZELIKS, Patrick Frenzel; GUIMARAES, Aline Silva; ALENCAR, Luciana Malta de; VENTURA, Dora Selma Fix; ALVES, Milton Ruiz; JOSÉ JÚNIOR, Newton KaraPURPOSE: Development and validation of quality of life questionnaire in pseudophakic patients in Portuguese. METHODS: The modified Cataract TyPESpecification questionnaire was specifically developed to assess quality of life after cataract surgery, functional status evaluated with 10 items and contains 18 questions. All questions were applied by a single examiner, with the goal of graduating visual satisfaction from 0 to 10 (0 means very dissatisfied, 5 neutral, 10 very satisfied).This prospective comparative study included 142 eyes of 71 patients in Sao Paulo University. The ophthalmologic evaluation performed included near, intermediate and distance corrected and uncorrected visual acuity and quality of life questionaire. The minimum follow-up was 6 months. RESULTS: The mean age of patients was 60.7± 6.6 years in theTecnis®MF, 63.1 ±4.4 years in-groupRestor®63.7±4.2 years in-group SN60AT/SN60WF. Uncorrected and distance-corrected near visual acuity were statistically higher in theRestor® and Tecnis® groups compared to the SN60AT/SN60WF group (p<0.001). There were no statistical differences between groups comparing uncorrected and best-corrected distance visual acuity (p=0.56). Satisfaction questionnaire showed high glasses independence fortheTecnis®MF (9.3 /10) and Restor® (8.7 /10), but with more unsatisfied of halos (18.8% Restor®, Tecnis®21, 7%) and glare (Restor® 25%;Tecnis®26.1%) than the group SN60AT/SN60WF. CONCLUSION: Cataract patients who received multifocal (Restor®; Tecnis®MF) IOLs at time of surgery obtained better uncorrected and distance corrected near visual acuity and reported better overall vision, less limitation in visual function, less spectacle dependency, and more glare or halo than those who received monofocal (SN60AT; SN60WF) IOLs. Cataract TyPESpecification questionnaire was a strong predictor of change in patient satisfaction caused by cataract surgery.
- Prospective randomized comparative study between venturi and peristaltic pumps in WhiteStar Signature (R) phacoemulsification machine(2019) HIDA, Wilson Takashi; MEDEIROS, Andre Lins de; ROLIM, Andre Gustavo de Araujo; MOTTA, Antonio Francisco Pimenta; KNIGGENDORF, Danilo Varela; QUEIROZ, Rodrigo Lafeta Franco de; CHAVES, Mario Augusto Pereira Dias; CARRICONDO, Pedro Carlos; NAKANO, Celso Takashi; NOSE, WaltonPurpose: To compare intraoperative parameters between venturi and peristaltic pump in WhiteStar Signature (R) phacoemulsification machine using the bevel-down technique. Setting: Hospital Oftalmologico de Brasilia, Brasilia, Federal District, Brazil. Design: Prospective, comparative, patient-masked study. Methods: Three hundred eyes were randomly assigned to have a phacoemulsification procedure with WhiteStar Signature (R) using either peristaltic (n=150 eyes) or venturi (n=150 eyes) pumps by a single surgeon (WTH). Elliptical ultrasound setting and prefracture (prechop or preslice) techniques were used in all cases. Cataract nucleus density was graded using lens opacities classification system III and Pentacam Nucleus Staging classification. Clinical measurements included preoperative- and postoperative-corrected visual acuity, preoperative and 2-month postoperative endothelial cell counts, and preoperative and 1-day postoperative central corneal thickness. Intraoperative measurements at the end of the case were phaco time, fluid used, total case time, and Efx energy. Results: There were no statistically significant differences between groups regarding age, cataract density, and phaco time (P>0.05). Intraoperatively, we observed significantly less ultrasound energy (P=0.011), case time (P=0.0001), and balanced saline solution (P=0.001) usage in the venturi group. Clinically, both fluidic settings can provide similar clinical outcomes and visual recovery, regarding corrected distance visual acuity, endothelial cell count, and central corneal thickness. Conclusion: Our data show that to minimize fluid use, case time, and energy with the prefracture technique, the venturi pump was the most efficient system and was statistically superior to peristaltic pump.
- Outcomes study between femtosecond laser-assisted cataract surgery and conventional phacoemulsification surgery using an active fluidics system(2017) HIDA, Wilson Takashi; TZELIKIS, Patrick Frenzel; VILAR, Cesar; CHAVES, Mario Augusto Pereira Dias; MOTTA, Antonio Francisco Pimenta; CARRICONDO, Pedro Carlos; VENTURA, Bruna Vieira; AMBROSIO JUNIOR, Renato; NOSE, Walton; ALVES, Milton RuizPurpose: The purpose of this study was to compare intraoperative parameters between femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification using Centurion (R) Vision System with Active Fluidics. Setting: This study was performed at Brasilia Ophthalmologic Hospital, Brasilia, Federal District, Brazil. Patients and methods: This was a prospective randomized comparative study. Patients with the diagnosis of cataract and surgical extraction programmed were divided into two groups: conventional phacoemulsification and FLACS. Intraoperative data were collected and submitted for statistical analysis. Results: A total of 400 eyes were enrolled, 200 in each group. There were no surgical complications. Groups were statistically equivalent in age and nucleus density. Cumulative dissipated energy and torsional time were significantly reduced in the FLACS group. Conventional surgery had less fluid usage, total case time and aspiration (ASP) time. Conclusion: FLACS with Active Fluidics System can reduce the ultrasound energy use during cataract surgery, in spite of increasing case time, fluid usage and ASP time.

Methods: Thirty-seven patients with cataract without other ocular diseases were randomly assigned to Groups A and B before phacoemulsification. Group A received topical gatifloxacin 0.3% same-day surgery and Group B received gatifloxacin 0.3% four times a day three days before phacoemulsification. After the procedure the aqueous humor was aspirated for cultures on agar-blood, agar-chocolate, saboraud and TSB and smeared for bacterioscopy. Results: Group A presented 40% of the bacterioscopies with cocci gram +, Group B presented 17.6% of the bacterioscopies with cocci gram +. These results are not statistically significant (p=0,098). Five cases (25%) from Group A presented positive cultures for S. epidermidis, which was significantly higher than Group B, which did not present positive cultures for any bacteria or fungus (p=0,027). Conclusion: Gatifloxacin 0.3% applied three days before phacoemulsification significantly lowered the rate of positive aqueous humor cultures when compared to immediate application of this antibiotic before surgery in this study.- Intraindividual comparison of nepafenac 0.3% for the prevention of macular edema after phacoemulsification(2018) TZELIKIS, Patrick Frensel; MORATO, Clezio S.; NEVES, Nathalia Teles; HIDA, Wilson Takashi; ALVES, Milton RuizPurpose: To compare the antiinfiammatory efficacy of topical nepafenac 0.3% for prophylaxis of macular edema after cataract extraction. Setting: Sao Paulo University, Sao Paulo, Brazil. Design: Prospective randomized clinical trial. Methods: Patients with bilateral cataract were included in this study. Each patient was assigned randomly to receive nepafenac 0.3% drops in 1 eye and a placebo in the fellow eye. The primary outcome measure was the change in the mean spectral-domain optical coherence tomography central subfield thickness 5 weeks postoperatively. The secondary outcome measures were the total macular volume 1, 5, and 12 weeks postoperatively; the percentage of patients in both groups who developed macular edema, and the corrected distance visual acuity within 5 weeks and 12 weeks after cataract surgery. Results: The study comprised 224 eyes of 112 patients. For all retinal thickness measurements, a significant increase in both groups was detected starting from the first postoperative week until 12 weeks. At 5 weeks, there was a statistically significant difference in central subfield thickness and total macular volume between the nepafenac group and control group (P = .01 and P < .001, respectively). At the fifth postoperative week, no eye in the nepafenac group and 4 eyes (3.57%) in the control group had macula edema, highlighting a trend toward a greater incidence in the control group. The between-group differences in visual outcomes were not statistically significant. Conclusion: Used prophylactically after cataract surgery, nepafenac 0.3% was efficacious in reducing macular thickness compared with a placebo 5 weeks postoperatively, without a difference in final visual acuity.
- Comparison of visual outcomes after bilateral implantation of a diffractive trifocal intraocular lens and blended implantation of an extended depth of focus intraocular lens with a diffractive bifocal intraocular lens(2017) MEDEIROS, Andre Lins de; ROLIM, Andre Gustavo de Araujo; MOTTA, Antonio Francisco Pimenta; VENTURA, Bruna Vieira; VILAR, Cesar; CHAVES, Mario Augusto Pereira Dias; CARRICONDO, Pedro Carlos; HIDA, Wilson TakashiPurpose: The purpose of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ (R) PanOptix (R) TNFT00 (group A), and blended implantation of an extended depth of focus lens, J&J Tecnis Symfony (R) ZXR00 with a diffractive bifocal intraocular lens, J&J Vision Tecnis (R) ZMB00 (group B). Methods: This prospective, nonrandomized, consecutive, comparative study included the assessment of 40 eyes in 20 patients implanted with multifocal intraocular lens. Exclusion criteria were existence of any corneal, retina, or optic nerve disease, previous eye surgery, illiteracy, previous refractive surgery, high axial myopia, expected postoperative corneal astigmatism of >1.00 cylindrical diopter (D), and intraoperative or postoperative complications. Binocular visual acuity was tested in all cases. Ophthalmological evaluation included the measurement of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), and uncorrected intermediate visual acuity (UIVA), with the analysis of contrast sensitivity (CS), and visual defocus curve. Results: Postoperative UDVA was 0.01 and -0.096 logMAR (p<0.01) in groups A and B, respectively; postoperative CDVA was -0.07 and -0.16 logMAR (p<0.01) in groups A and B, respectively; UIVA was 0.14 and 0.20 logMAR (p<0.01) in groups A and B, respectively; UNVA was -0.03 and 0.11 logMAR (p<0.01) in groups A and B, respectively. Under photopic conditions group B had better CS at low frequencies with and without glare. Conclusion: Both groups promoted good quality of vision for long, intermediate, and short distances. Group B exhibited a better performance for very short distances and for intermediate and long distances >=-1.50 D of vergence. Group A exhibited a better performance for UIVA at 60 cm and for UNVA at 40 cm.
- Comparison between bilateral implantation of a trifocal intraocular lens and blended implantation of two bifocal intraocular lenses(2017) VILAR, Cesar; HIDA, Wilson Takashi; MEDEIROS, Andre Lins de; MAGALHAES, Klayny Rafaella Pereira; TZELIKIS, Patrick Frensel de Moraes; CHAVES, Mario Augusto Pereira Dias; MOTTA, Antonio Francisco Pimenta; CARRICONDO, Pedro Carlos; ALVES, Milton Ruiz; NOSE, WaltonPurpose: To compare visual outcomes and performance between bilateral implantation of a diffractive trifocal intraocular lens (IOL) Acrysof (R) PanOptix (R) TFNT00 and blended implantation of two different near add power bifocal IOLs: Acrysof (R) Restor (R) SV25T0 in dominant eye and Acrysof (R) Restor (R) SN6AD1 in the nondominant eye. Methods: This prospective, nonrandomized, consecutive and comparative study assessed 20 patients (40 eyes) who had bilateral cataract surgery performed using the IOLs described. Patients were divided into groups, bilateral trifocal implant and blended implant. Evaluation included measurement of binocular uncorrected and corrected distance visual acuity at 4 m (UDVA, CDVA) and uncorrected intermediate (60 cm) and near (at 40 cm) visual acuity; contrast sensitivity (CS) and visual defocus curve. Results: Postoperative CDVA comparison showed no statistical significance between groups. UDVA was significantly better in the trifocal groups. Under photopic conditions, the trifocal group had better CS in higher frequencies with and without glare. The binocular defocus curve demonstrated a trifocal behavior in both groups, with the bilateral trifocal group exhibiting better performance for intermediate vision. Conclusion: Both lens combinations were able to provide good near, intermediate and distance vision, with the trifocal group showing significantly better performance at intermediate distances and better CS under photopic conditions.
- Técnica Tied Out Open Sky: fixação iriana de lente intraocular combinada com transplante penetrante de córnea(2012) ANTUNES, Victor Andriguetti Coronado; HIDA, Wilson Takashi; SOUSA, Danilo da Costa; YAMANE, Iris; MORO, Fernando; MOYSES, Karine Borges Marques; CVINTAL, Tadeu; ALENCAR, Luciana Malta de; NAKANO, Celso Takashi; TZELIKIS, Patrick FrenselTo describe a new method for iris fixation of intraocular lens in the absence of capsular support during penetrating keratoplasty. Its a new technique of iris fixation of intraocular lens without capsular support during penetrating keratoplasty. This technique is used in cases with a healthy iris and partial or total absence of capsular support during penetrating keratoplasty. Tied Out Open Sky is a technique easy to perform for iris fixation of intraocular lens during penetrating keratoplasty. The big advantage is being able to tie off the intraocular lens off the eye and fasten it securely.
- Architecture evaluation of the main clear corneal incisions in femtosecond laser-assisted cataract surgery by optical coherence tomography imaging(2019) CHAVES, Mario Augusto Pereira Dias; MEDEIROS, Andre Lins de; VILAR, Cesar Martins Cortez; MAGALHAES, Klayne Rafaella Pereira; GONCALVES, Michelle Rodrigues; TZELIKIS, Patrick Frenzel de Moraes; HIDA, Wilson Takashi; CARRICONDO, Pedro Carlos; ALVES, Milton RuizPurpose: To assess the stability and reliability of femtosecond laser-assisted cataract surgery (FLACS) incisions design and dimensions using anterior segment optical coherence tomography (AS-OCT) imaging. Setting: Renato Ambrosio Ophthalmologic Study Center from Hospital Oftalmologico de Brasilia, Brasilia, Brazil. Design: Prospective nonrandomized controlled case series. Methods: Eyes undergoing FLACS with triplanar main temporal clear corneal incision (CCI) were evaluated at the end of the case. Eyes that required any incision hydration, surgical complications or lacked follow-up were excluded. The AS-OCT was performed after femtosecond delivery; at the end of the case; at 1 day and at 30 days after surgery. Data of pachymetry, endothelial and epithelial gaps, Descemet detachment and CCI architecture were compared. Results: Eleven eyes from 11 patients completed follow-up. Corneal thickness was statistically different between after femtosecond delivery and the end of the case (P-value <0.05), but without difference compared to 30 days evaluation. There was an increase of Descemet detachments (P-value,0.05) and endothelial gaps (P-value =0.0133) at the end of the case compared to post-femtosecond delivery. As for the architecture of the CCI, significant difference was found between the parameters of entry angle and exit angle measured with AS-OCT and the programmed. Conclusion: The AS-OCT was capable of visualizing changes in the cornea at the CCI. Despite the stress caused by manipulation, results indicated good stability of incision and reproducibility of tunnel length. Synopsis: Difference of corneal thickness at the CCI between after femtosecond and after phacoemulsification measurements (P-value,0.05), with increase of endothelial gaps (P-value =0.0133) and Descemet detachments (P-value,0.05).
