Abstract
PCO, which is called “secondary cataract”, is the most widespread complication of cataract extraction procedures. The formation of PCO is a dynamic process that involves three basic phenomena: proliferation, migration, and differentiation of the residual lens epithelial cells after removal of the nucleus in cataract extraction procedures.PCO has three pathological types: pearl type, fibrotic type, and mixed type.
Nd:YAG laser capsulotomy is the gold standard treatment of PCO because it can be applied rapidly under polyclinic conditions, and has a high success rate of more than 95%. However, various complications were reported such as IOL dislocation, IOL pitting, CME, rise in the IOP, retinal detachment, corneal injury, and endophthalmitis.
This prospective interventional study included 40 pseudophakic eyes of forty patients who were treated by Nd:YAG laser posterior capsulotomy due to posterior capsular opacification. the influence of Nd:YAG laser posterior capsulotomy size on the visual outcomes, S/E, IOP, and CMT was evaluated.
All patients underwent a complete ocular examination before the Nd:YAG laser capsulotomy, 1 week, 1 month, and 3 months after Nd:YAG laser capsulotomy including BCVA, refraction, IOP measurement, anterior segment slit-lamp examination and posterior segment examination by slitlamp biomicroscopy.
The capsulotomy size was determined by the physician concerning optical, and mechanical factors that depend on scotopic pupil size and the size of the IOL. Therefore, the capsulotomy was carried out equal to or.
