A Comparative Longitudinal Study To Evaluate The Changes In Intra Ocular Pressure, After Manual Small Incision Cataract Surgery Between Pre-Operative And Post-Operative Period

Abstract

Aim :To evaluate the effect of manual small incision cataract surgery (MSICS) on intraocular pressure (IOP) by comparing preoperative values with postoperative values at different time intervals. Additionally, to assess the impact of different ophthalmic viscoelastic devices (OVDs), specifically hydroxypropyl methylcellulose 2% (HPMC) and sodium hyaluronate 1.4%, on postoperative IOP. Ophthalmic viscoelastic devices (OVDs) are essential in ophthalmic surgeries including cataract surgeries for corneal endothelium protection, maintaining the anterior chamber, and facilitation of intraocular lens implantation. However, their retention postoperatively can cause transient IOP (intraocular pressure) elevation. The impact of different OVDs on IOP varies based on their rheological properties (viscosity, cohesion, dispersion). Present study evaluated and compared the value of intraocular pressure before and after manual small incision cataract surgery.
