- Comparison of different surgical approaches for pediatric cataracts: complications and rates of additional surgery during long-term follow-up(2019) KOCH, Camila R.; KARA-JUNIOR, Newton; SANTHIAGO, Marcony R.; MORALES, MartaOBJECTIVES: To compare long-term postoperative complications of pediatric cataract surgery with primary intraocular lens (IOL) implantation associated with posterior capsulotomy (PC) and anterior vitrectomy (AV) between patients treated with a corneal or pars plicata/pars plana approach. METHODS: Children who underwent cataract surgery with in-the-bag primary IOL implantation were divided into two groups according to PC and AV surgical approach: a corneal approach (group 1) and a pars plicata/pars plana approach (group 2). Only patients with a follow-up duration of more than two years were included. Longterm surgical outcomes were retrospectively reported. RESULTS: The mean follow-up period was 10.00 +/- 3.13 years. No cases of glaucoma or retinal detachment were reported. The mean age at surgery was 34.57 +/- 22.66 months. Forty-six children were included (27 eyes in group 1 and 29 eyes in group 2). The most frequent postoperative complication was corectopia, followed by visual axis opacification. Both complications occurred more frequently in group 1 (p < 0.001). After cataract surgery, the rate of additional surgeries in group 1 was 51.9%, while in group 2, the rate was 27.6% (p=0.1132). CONCLUSION: The pars plicata/pars plana approach with PC and vitrectomy with primary in-the-bag IOL implantation for pediatric cataracts is a safe procedure.
- Outcomes of Toric Iris-Claw Phakic Intraocular Lens Implantation After Deep Anterior Lamellar Keratoplasty for Keratoconus(2017) TIVERON JR., Mauro C.; BARRIO, Jorge L. Alio del; KARA-JUNIOR, Newton; PLAZA-PUCHE, Ana Belen; ABU-MUSTAFA, Sabat K.; ZEIN, Ghassan; ALIO, Jorge L.PURPOSE: To assess visual and refractive outcomes of toric iris-claw phakic intraocular lens (IOL) implantation in patients who had previously undergone deep anterior lamellar keratoplasty (DALK). METHODS: Retrospective case series including 24 eyes of 24 patients implanted with toric Artiflex or Artisan (Ophtec BV, Groningen, Holland) phakic IOL following DALK for keratoconus. During a 12-month follow-up, the main outcome measures were uncorrected and corrected distance visual acuities (UDVA and CDVA), refractive error components, topographic parameters, and endothelial cell count. Alpins vectorial analysis was performed. RESULTS: At the last follow-up, the spherical equivalent (SE) was within +/- 0.50 diopters (D) in 71% of eyes and within +/- 1.00 D in 92% of eyes. Mean refractive astigmatism was reduced from -4.92 +/- 1.55 D (range: -2.50 to -8.00 D) preoperatively to -0.66 +/- 0.61 D (range: -2.00 to 0.00 D) after treatment, and 76.5% of cases were within +/- 1.00 D. No significant differences (P =.123) were detected in spherical equivalent values between 3-and 12-month follow-up visits. No eyes lost lines in CDVA, and 54% of eyes gained one or more lines. Postoperative UDVA was 20/40 or better in 88% of eyes. Efficacy and safety indexes at 12 months were 0.93 and 1.00, respectively. Mean endothelial cell loss was 6.10% at 12 months postoperatively. No intraoperative or postoperative complications were noted over the follow-up period. CONCLUSIONS: The implantation of a toric iris-claw phakic IOL has shown high efficacy and safety in this series and may be considered as a reasonable option for the management of refractive errors after DALK.
- Long-term results of secondary intraocular lens implantation in children under 30 months of age(2018) KOCH, Camila R.; KARA-JUNIOR, Newton; SERRA, Alicia; MORALES, MartaPurpose To report the long-term outcome of early secondary intraocular lens (IOL) implantation following congenital cataract extraction in a large number of eyes. Methods Data of aphakic children under 30 months of age who underwent secondary IOL implantation and had at least one year of follow-up after the surgery was reviewed. In all of the patients, a foldable three-piece acrylic IOL was implanted in the ciliary sulcus by the same surgeon using the same technique. The database studied included refractive and visual acuity (VA) outcomes and complications. Results Fifty patients (75 eyes) were included. The average age at the time of cataract extraction was 94.20 +/- 44.94 days and 20.7 +/- 6.0 months in the secondary IOL implantation. After 82.32 +/- 48.91 months, the VA was 0.58 +/- 0.35 LogMAR and the spherical equivalent was -2.20 +/- 4.19 D. There was a negative correlation between a longer follow-up period and myopia at the SE measured (P = .001). The most frequent complications included glaucoma and corectopia. Performing the secondary IOL implantation 20 months of age was not a risk factor for glaucoma development (P = 0.095). Conclusion Secondary IOL implantation under 30 months of age is an option for children with unsatisfactory management of the optic treatment. A predictable IOL power calculation and satisfactory visual outcomes compared to results of later secondary IOL implantation are possible.
