To Compare Changes in Intraocular Pressure in Glaucomatous and Non Glaucomatous Subjects Pre and Post Phacoemulsification

Background and objectives: Cataract and glaucoma are the first and second leading cause of blindness worldwide1-3. Intraocular pressure is the only known modifiable risk factor in management of glaucoma3. This prospective observational study was done to study changes in intraocular pressure in glaucomatous and non glaucomatous eyes undergoing phacoemulsification with intraocular lens implantation. Methods: 75 glaucomatous and 75 non glaucomatous subjects were evaluated in the eye OPD of tertiary care centre from January 2020 to September 2021. Evaluation included assessment of intraocular pressure in the eye undergoing phacoemulsification pre and post operatively on day 1, day 7, 1 month, 3 month and 6 month along with collection of basic information like age, sex. Results: The mean intraocular pressure at day 1, Day 7, 1 month, 3 month and 6 month was significantly more among glaucomatous. Interpretation & Conclusion: Phacoemulsification results in IOP reduction. In cases of higher preoperative IOP, phacoemulsification and Intraocular lens implantation is a reliable option for IOP control.
