NARANJO FERNANDEZ, Rosa María et al. Foldable intraocular lenses and postsurgical astigmatism in pediatric cataract. Rev Cubana Oftalmol [online]. 2013, vol.26, suppl.1, pp.345-352. ISSN 0864-2176.

Objective: to determine the postsurgical astigmatism in patients operated on from pediatric cataract and with foldable intraocular lens implantation. Methods: an observational, descriptive and cross-sectional study of 20 patients (28 eyes) between 2 and 14 years of age, who were operated on in the period of January 2008 through September 2010 at "Ramon Pando Ferrer" Cuban Institute of Ophthalmology. Some patients were excluded if they presented corneal alterations. Lensectomy, posterior capsulotomy and anterior vitrectomy were performed; hydrophobic and hydrophilic acrylic lenses were implanted. Results: fifty five percent of patients were 5 to 8 years of age (average of 5.7 years). The more frequent type of cataract was the congenital (85%). The initial visual acuity in 60.7 % of cases was below 0.3; four months after surgery, 32.1 % reached over 0.9 and after a year 35.7 % reached more than 0.9, and 28.6 % from 0.3 to 0.6. The astigmatism before the surgery in 32.2 % of cases ranged 0.5 to 1.5, but four months and one year after surgery, it was 0.5 to 1.5 in 35.7 % of patients. Conclusions: astigmatism did not vary with the performance of this type of surgery. A personalized surgical strategy allows achieving better anatomical and functional recovery of these patients.
