Abstract:
AlM:To compare the effect of different incision in corneal astigmatism after phacoemulsification.
METHODS: Totally 88 cases ( 122 eyes ) with pure cataract were randomly divided into two groups. Forty cases (60 eyes) were clarity corneal incision in group A, and 48 cases ( 62 eyes ) were sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism ( SlA ) , uncorrected visual acuity ( UCVA ) and best correct vision acuity ( BCVA ) were observed in pre- and post-operation at 1d;1wk;1mo.
RESULTS: The mean astigmatism had statistically significant difference between two groups at 1d; 1wk;1mo after operation(P<0. 05). The SlA had statistically significant difference at 1d ( P<0. 05 ); The SlA had no statistically significant difference between two groups at 1mo after operation (P>0. 05). UCVA≥0. 5 and BCVA≥0. 8 had statistically significant difference at 1d; 1wk ( P<0. 05) . There had no statistically significant difference at 1mo after operation (P>0. 05).
CONCLUSlON: Phacoemulsification with scleral tunnel incision remove combined intraocular lens ( lOL ) implantation has small changes to corneal astigmatism. By selecting personalized corneal incision according to the corneal topography might be more beneficial.
