Methodology: A total of 123 cataract patients were included in this study. Pre-operative keratometric readings were compared with post-operative readings, after a clear corneal incision (CCI) of 2.8mm made during phacoemulsification procedure. Opposite clear corneal incision was made in astigmatism over 1 diopter.</p> <p><strong>Results:</strong> Patients were monitored for six weeks post-operatively. It showed that a reduction of cylinder (0.81 ± 0.60 vs. 0.92 ± 0.54, p0.035) was present if the incision was at or near the steeper meridian. In 99 patients (80.4%) the astigmatism remained the same or there was a reduction in the power of preoperative cylinder. The remaining 24 patients had either no preoperative astigmatism in 11 patients, (8.94%), or the power of cylinder increased in 13 patients (10.57%) secondary to surgically induced astigmatism (SIA). Temporal clear corneal incision (CCI) made a lesser impact on the surgically induced astigmatism (SIA) than other quadrants.</p> <p><strong>Conclusion:</strong> The results confirmed that steeper axis clear corneal incision (CCI) CCI is effective in reduction of post-operative astigmatism. These incisions in conjunction with surgeon’s surgically induced astigmatism (SIA) play an important role in predicting postoperative visual outcome.</p>}, number={4}, journal={Pakistan Armed Forces Medical Journal}, author={Naeem, Saquib and Akram, Amjad and Parveen, Shagufta}, year={2020}, month={Aug.}, pages={923–27} }
