Evaluation of Intra-Ocular Pressure and Macular Thickness Post Nd Yag Laser Treatment in Patients With Posterior Capsular Opacification.

Background: - Posterior capsular opacication (PCO), also known as “SECONDARY CATARACT”, is one of the most common sequalae following cataract surgery. This can cause a gradual decline in visual acuity and glare. PCO is removed using ND YAG laser. While generally safe, this procedure carries risks such as increased intraocular pressure, cystoid macular edema, and retinal detachment, necessitating careful patient selection and follow-up. Sample design: - Purpose: - Hospital-based interventional study. Evaluation change of intra-ocular pressure and macular thickness post ND YAG laser treatment in patients with posterior capsular opacication. We enrolled Methods: - 50 participants aged between 45 to 75 years, who were evaluated for SECONDARY CATARACT, and subjected them to ND YAG laser capsulotomy. Intraocular pressure using goldmann applanation tonometry and 5 line OCT macula scan was done before , 1 hr after and 1 week after the procedure. All the patients were subjected to pupillary dilatation before the procedure using eye drops Tropicamide (0.8%) + Phenylephrine (5%) and eye drops Ciplox (0.3%) – Dexamethasone (0.1%) 3 times a day for 7 days followed by 2 times a day for 7 days and Timolol (0.5%) 2 times a day for 2 weeks after the procedure. Results: - A total of 50 eyes were included. 24% of the patients showed slight rise in intraocular pressure (4mmHg from their base line) which got resolved within 1 week of topical medications and only 4% showed increased macular thickness. The present stu Conclusion: - dy depicts the ND YAG laser capsulotomy as a good, successful treatment of PCO because it was found to be modern, noninvasive , effective mode of treatment of PCO with lesser complications and it does not require hospitalization.
