Refraction and Intraocular Pressure Changes After YAG Laser Posterior Capsulotomy in Posterior Capsular Opacification

Abstract

Background: Posterior capsular opacification (PCO), often known as "secondary cataract" PCO is Formed by remained sub-capsular epithelial lens cells which migrate, proliferate and differentiate leading to opacity with drop of vision and other visual disturbance as blurring specially when it involves visual axis. Aim of TheWork: To investigate the Effect of YAG Laser Capsulotomy for Posterior Capsular Opacification in Pseudophakic eyes on Refraction, Astigmatism and Intraocular Pressure of Patient before and after treatment. Patients and Methods: This study conducted on 50 eyes of 36 patients with PCO attending the outpatient ophthalmology clinic of Al-Azhar University hospitals (Cairo branch) during the period from March 2021 to December 2021.Results: A statistically significant improvement in UCVA, BCVA, refraction, and IOP was found at follow-up compared to pre-session (p-value<0.05), but no change in Cylinder, Axis, or K readings. Conclusion:The Nd: YAG laser capsulotomy approach is a noninvasive outpatient treatment option for PCO that significantly improves UCVA and BCVA while having a little effect on refraction and IOP. It is straightforward, quick, and typically safe.

Refractive Changes after Nd.YAG Laser Capsulotomy in Pseudophakic Patients

“…There was no significant difference in corneal topography k1 readings between pre-session and post-session, with the highest value in pre-session [44.29±1.54] and lowest in post-session [43.79±1.37], with a mean difference of -0.50. However, there was a significant difference in pre-session and average k readings [44.68±1.24] [19]. Patients' spherical equivalent values dropped post-YAG capsulotomy, but hyperopia increased post-capsulotomy, possibly due to the procedure's width, according to Karahan et al [10,20].…”
