Title : Post operative central corneal thickness changes in phacoemulsification with pciol
Abstract:
Blindness is the major concern globally which leads to poor quality of life and various other problems. Cataract surgery is the commonest type of eye surgery performed throughout the world. Phacoemulsification with an intraocular lens is the most commonly performed surgery used to treat the cataract and restore vision. The present study was undertaken to evaluate the post operative central corneal thickness changes after phacoemulsification with PCIOL in different grades of cataract using anterior segment OCT. The present cross-sectional observational study was conducted in the Kapoor Eye Care Jammu w.e.f November, 2020 to December, 2022. A total number of 150 patients were categorized into 3 categories according to WHO classification, i.e. Group A NS1+/NS2+/PSC, Group B NS 3+ and Group C NS4+ and evaluated postoperatively.
The mean CCT as measured one day before the surgery was found to be 539.84±5.83 microns, in Group-B mean CCT was found to be 542.86±7.67 microns, and in Group-C the mean was found to be 542.52±6.22 microns.
The highest average increase of 7.47% and 40.32 microns was observed at 24 hours after surgery which showed a gradual and constant fall with values reaching the pre-operative level by day 7 in Group A. The highest average increase of 12.85% and 69.8 microns was observed at 24 hours after surgery which showed a gradual and constant fall with values reaching the pre-operative level by day 14 in Group B. The highest average increase of 18.03% and 97.84 microns was observed at 24 hours after surgery which showed a gradual and constant fall with values reaching the approximate pre-operative level by day 28 in Group C. The Effective Phacotime (EPT) was found to be :-
- EPT of Group A = 171.12±42.39 seconds
- EPT of Group B = 208±44.84 seconds
- EPT of Group C = 314.32±48.97 seconds
