Changes in Intra Ocular Pressure after Phacoemulsification with intraocular lens implantation.

Abstract

Objectives: To study the changes in intra ocular pressure (IOP) after phacoemulsification with intra ocular lens implantation. Study Design: Quasi experimental study. Setting: Lahore General Hospital, Lahore. Period: From 1-3-2017 to 30-9-2018. Material & Methods: The study was conducted after getting approval from ‘’Ethical Review Board’’ of Lahore General Hospital, Lahore. Patients presenting to the Eye OPD Lahore General Hospital were assessed for inclusion and exclusion criteria. All patients (n=) diagnosed with cataract significantly decreasing vision were selected. Patients having any coexisting ocular pathology i.e. corneal opacity, Glaucoma etc. were excluded from study. Pre operatively intraocular pressure was measured on slit lamp with the applanation tonometry. The patients were called for follow-up after at which time Visual acuity and intraocular pressure was again measured and findings recorded in the proforma. All the surgeries were performed by single surgeon. Results: Pre-operative mean intra ocular pressure was 22.02±1.403 mm Hg which reduced significantly to 20.39±1.363mm Hg, 19.61±1.418mm Hg, 18.94±1.738mm Hg after one day, one week and one month of surgery respectively. Conclusion: Phacoemulsification cataract surgery leads to a decrease in intraocular pressure.
