Purpose: To see the effect of Nd: YAG laser capsulotomy on intraocular pressure (IOP), refraction, bestcorrected visual acuity (BCVA), anterior chamber depth (ACD), and macular thickness. Methodology: The authors conducted a prospective, descriptive study on pseudophakic eyes with posterior capsule opacification who underwent Nd: YAG laser capsulotomy. BCVA, IOP, spherical equivalent (SE), macular thickness and ACD were noted preoperatively at 1 hr postoperatively and at 1-month follow-up. Patients were divided into two groups based on energy used (Group I ≤50 mJ, Group II >50 mJ). None of the patients received prophylactic anti-glaucoma medications either before or after the procedure. Results: There were 96 eyes of 83 patients. Mean total energy levels were 26.64±12.92 mJ in Group I and 81.96±32.10 mJ in Group II. BCVA at 1 hr and 1 month postoperatively improved significantly in both the groups compared to preoperative BCVA (P<0.001). There was no significant change in SE compared to preoperative values in both the groups. The ACD continued to increase significantly in both the groups at both 1 hr and 1-month follow-up. In Group I, IOP increased at 1 hr postoperatively (P=0.023) and declined to preoperative levels at 1 month. In Group II, IOP increased at 1 hr postoperatively (P<0.001) and did not return to preoperative levels at 1-month follow-up (P=0.003). Likewise, macular thickness increased at 1 hr in both groups (P<0.001). In Group I, macular thickness decreased significantly to preoperative level at 1 month whereas in Group II, it remained significantly high at 1-month follow-up (P=0.006). There was no case with serious rise in IOP or cystoid macular edema. Conclusions: Statistically significant increment in IOP and macular thickness occurs after Nd: YAG laser capsulotomy which however may not necessitate the use of any medications.
