Abstract
Purpose: To assess the role of surgical peripheral iridectomy (PI) in preventing iris-related complications associated with glued intraocular lens (GIOL) surgery in children with bilateral ectopia lentis.
Methods: Nonrandomized interventional case series of 34 eyes of 17 children (<15 years of age) who underwent pars plana lensectomy (PPL) and GIOL surgery between January 2013 and December 2016. Eyes with surgical PI (January 2013–June 2015) were compared with those without surgical PI (July 2015–December 2016). The primary outcome measure of the role of surgical PI in GIOL surgery was to account for complications such as optic capture, secondary glaucoma, intraocular lens (IOL) dislocation, or repeat surgery. The secondary outcomes were changes in the best-corrected visual acuity (BCVA).
Results: The mean age at surgery was 8.8 years (range: 3.5–15 years). Surgical PI was conducted in 15 eyes. Among the 19 eyes without PI, 9 eyes had complications (optic capture –6; rise in IOP –4; IOL subluxation –4; repeat surgery –5). The complications were significantly less in the PI group, P = 0.02. There was a statistically significant improvement in BCVA (P = 0.0001) in all the patients. The mean presenting BCVA was 0.99 (±0.79) logMAR (Snellen ? 20/200) and post BCVA was 0.40 (±0.50) (Snellen ? 20/50). The mean preoperative refraction was ? 9 D (±8D) (range: ?5 D to ?23D) and postoperative was ?1 (±1.15) D. The mean follow-up was 25.4 months.
Conclusion: Surgical PI along with GIOL surgery in children undergoing PPL is shown to reduce optic-capture-related complications.
