Which procedure has more effect on macular thickness: primary posterior continuous capsulorhexis (PPCC) combined with phacoemulsification or Nd:YAG laser capsulotomy?

To compare the effect of Nd:YAG laser capsulotomy and primary posterior continuous capsulorhexis (PPCC) combined with phacoemulsification on macular thickness using optical coherence tomography (OCT) in adults. This prospective comparative interventional study included 32 eyes of 30 patients who underwent Nd:YAG laser capsulotomy and 33 eyes of 33 patients who underwent cataract surgery with PPCC. Detailed ocular examinations, including macular thickness measurements by OCT, were performed in all patients preoperatively and postoperatively on the 1st day, 1st week, and 1st, 3rd and 6th months. No significant differences were found in macular thickness between the two groups in preoperative and postoperative follow-up. No cystoid changes were observed in OCT during the postoperative period in both groups. Nd:YAG laser capsulotomy and PPCC combined with cataract surgery are safe and effective procedures that are not associated with an increase in macular thickness.
