The effect of manual small incision cataract surgery on the intraocular pressure – A prospective study in south Kerala

Aim: To study the effect of manual small incision cataract surgery (SICS) on the intraocular pressure (IOP) postoperatively at one week, three weeks and three months. Materials and Methods: Prospective longitudinal study, conducted at Dr SMCSI College from January 2016 –May 2017. Sample size: 50 eyes. Patients who underwent uneventful SICS were included. Patients with pre-existing glaucoma, were excluded. Goldman applanation tonometer was used to measure IOP. Preoperative IOP was measured. All patients underwent manual SICS with PCIOL implantation by one surgeon. Postoperative IOP measurements were taken at one week, three week, and three month postoperatively. Analysis done using SPSS 16.0. Results: The mean preoperative IOP was 15.16(SD +/- 2.566) mm Hg. The mean one week postoperative IOP was 14.08 (SD +/- 2.320) mm Hg. The mean postoperative IOP at three weeks was 13.68 (SD +/- 2.343) mm Hg. The mean postoperative IOP at three month was 13.12 (SD +/- 2.496) mm Hg. Paired sample t-test showed p <0> Conclusion: There was significant reduction in intraocular pressure after manual SICS.
