Abstract

INTRODUCTION
Posterior capsular opacification (PCO) is the most common long‐term complication of cataract surgery in both phacoemulsification and extracapsular cataract extraction (ECCE).
Some patients experience significant vision complications including decreased visual acuity, glare, and reduced contrast sensitivity, which often require further treatment. Currently, the standard treatment of PCO is Nd:YAG laser posterior capsulotomy, which has a success rate of more than 95%.
Nd:YAG laser posterior capsulotomy is the preferred treatment method in PCO with its economical, rapid and non‐invasive aspects.
Any significant change in IOL position can lead to a change in the patient’s refractive status, which will therefore require corrective lens prescriptions.

Aim of the work
The aim of our study is to evaluate the effect of Nd:YAG laser posterior capsulotomy on patient’s refraction.

Patients and Methods
This prospective interventional case series was conducted on 100 eyes who underwent uncomplicated phacoemulsification surgery.
Inclusion criteria
• Patients who underwent uncomplicated phacoemulsification surgery.
• Age: Above 40.
• Complete CCC (Continuous Curvilinear Capsulorhexis).
• Bagal Implanted IOL.
• Intra-Ocular Lens (IOL) diopteric power ranges from (12 - 26 D).
• Clear cornea.
• Free posterior segment.
Exclusion criteria
• Patients with very small Capsulorhexis or capsular phimosis.
• Patients with corneal pathology such as scarring, keratoconus.
• Patients with previous history of intraocular surgery other than cataract surgery.
• Corneal refractive surgeries, Post DALK and PKP.
