Effect of micro - incision on corneal wavefront aberration and tear film in phacoemulsification
摘要
Abstract
AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film. <br> METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively. <br> RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative. <br> CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.关键词
