“…Seven of 15 trials reported BCVA at three months’ follow-up (Can 2010; Hwang 2008; Hwang 2016; Lin 2013; Moon 2011; Shan 2016; Wang 2009). Hwang 2008, Lin 2013, and Shan 2016 did not report the units of the BCVA measurement, which could be either decimal or logMAR units, therefore we did not include their data in the meta-analysis.…”

“…Hwang 2008, Lin 2013, and Shan 2016 did not report the units of the BCVA measurement, which could be either decimal or logMAR units, therefore we did not include their data in the meta-analysis. We also could not include Wang 2009’s BCVA data as it was reported as the percentages of participants that had greater or equal to 1.0 D, 0.8 D, or 0.5 D. The authors of Wang 2009 also noted that “postoperative uncorrected distance visual acuity tended to be better with the smaller incisions, but this trend did not reach statistical significance (P = 0.07).”…”

Purpose: The purpose of this study is to evaluate the effects of variation in tunnel length of same-sized clear corneal phacoemulsification incisions on the generation of surgically induced astigmatism and corneal astigmatism. Methods: A total of 126 cataract patients treated in four study groups based on location and tunnel length of the clear corneal incisions (superior long, superior short, temporal long, temporal short) were reviewed. In the short tunnel groups, a 2.8 mm keratome was used with a motion parallel to the iris surface, while in the long tunnel groups, the same keratome was advanced in the corneal stroma until the mark on the keratome was reached. The surgically induced astigmatism and the corneal astigmatism were measured with corneal topography. The tunnel lengths were determined by anterior segment optical coherence tomography. Results: The tunnel lengths of the long tunnel groups were significantly longer than the short tunnel groups. The total and anterior corneal surgically induced astigmatism of the superior long group was significantly higher than the other groups. Posterior corneal surgically induced astigmatism was similar. The postoperative total and anterior corneal astigmatism values of the superior long group was significantly higher than the other groups. No difference was observed for mean change in corneal astigmatism between the groups. Conclusion: The tunnel length of a clear corneal incision is a significant determinant of surgically induced astigmatism for superior placed corneal incisions. Therefore, for superiorly positioned clear corneal incision, the incision should be rectangular with a shorter tunnel to keep the surgically induced astigmatism to a minimum. For squarer-shaped clear corneal incision, limbal-temporal incisions may be performed for astigmatic neutrality.
