Comparison of surgically induced astigmatism after superotemporal and superonasal clear corneal incisions in post phacoemulsification

Objective: To compare the surgically induced astigmatism (SIA) of 2.75mm superotemporal and superonasal clear corneal incisions in post phacoemulsification. Methodology:This comparative cross-sectional study evaluated 60 eyes of 56 Malaysian subjects. Those who attended at least six weeks of po...

Kamal, Khairidzan Ab Halim, Noorhazayti RE Ophthalmology Objective: To compare the surgically induced astigmatism (SIA) of 2.75mm superotemporal and superonasal clear corneal incisions in post phacoemulsification. Methodology:This comparative cross-sectional study evaluated 60 eyes of 56 Malaysian subjects. Those who attended at least six weeks of postoperative follow-up visit were recruited in this study. The phacoemulsification procedure was performed using sutureless clear corneal incisions of 2.75mm size by three ophthalmic surgeons of International Islamic University Malaysia Eye Specialist Clinic, Kuantan, Pahang, Malaysia. Two surgeons have performed superotemporal incisions on the right eye and superonasal incisions on the left eye, while one surgeon has performed superotemporal incisions on the left eye and superonasal incisions on the right eye. Postoperative keratometry was measured by IOLMaster 700, whereas the preoperative keratometry was retrieved from subjects’ medical record. The SIA was calculated through Holladay's method of vector analysis using SIA 2.1 calculator. Results: Total number of subjects in superotemporal and superonasal group were 34 and 26 with mean preoperative astigmatism of 0.79 ± 0.47 D and 0.74 ± 0.83 D respectively, whereas mean postoperative astigmatism were 1.01 ± 0.52 D and 0.68 ± 1.04 D respectively. Vector analysis result showed that mean SIA were 0.72 ± 0.45 D for superotemporal incision and 0.81 ± 0.44 D for superonasal incision groups. However, there was no statistically significant difference between these two incision groups (p > 0.05). Conclusion: The selected location of incision did not influence the SIA value in postoperative phacoemulsification among Malaysian eyes. 2018-08-10 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/66698/7/OOC-2018.pdf Md Mustafa, Md Muziman Syah and Marzuki, Nazaryna and Mohd.
