Abstract
Purpose: To compare outcomes of cruciate and circular YAG capsulotomy techniques regarding: Best corrected Visual acuity (BCVA) improvement, significant change in IOP and central macular thickness.
Methods: A prospective comparative cohort including medically free patients with visually significant posterior capsular opacity who underwent uneventful cataract surgery more than 6 months ago. Divided to Group A: 110 eyes for cruciate YAG capsulotomy technique. Group B: 110 eyes for circular YAG capsulotomy technique. All patients underwent complete ophthalmological examination including BCVA, PCO examination , IOP measurement and central macular thickness (CMT)by OCT, performed before the procedure and one month afterwards. capsulotomies were done with an initial energy of 0.8 mJ and increased in increments of 0.2 mJ until a capsular opening was achieved.
Results: There was a significant higher values in total energy: 54.0(mJ) in cruciate group vs 42.5(mJ) in circular group, total number of shots in cruciate group was 14.38 vs 12.96 in circular group respectively . Both techniques improved BCVA from baseline values by LogMAR (0.64 ± 0.09, 0.64 ± 0.06 respectively to 0.13 ± 0.02, 0.14 ± 0.03 after a month,without a significant increase in IOP (16.51 vs 17.28 mmHg respectively) ,(16.09 vs 16.78mmHg ) after 1 month and CMT was( 258.79vs 254.65 μm respectively) at baseline and after 1 month was (257.4 vs 260.27 μm )with insignificant difference between the two groups.
Conclusion:
Both techniques proved to be efficient for clearing the visual axis in PCO but a higher Energy was needed in cruciate technique without clinical implication.
