Abstract:
?AlM: To compare the clinical effect between small-incision cataract surgery and phacoemulsification.
?METHODS: Totally 93 patients ( 124 eyes ) with age-related cataract who received treatment in Mar 2010 and Feb 2013 were dicided into 2 groups randomly. Forty-two patients ( 59 eyes ) in group small - incision cataract surgery ( SlCS ) were treated by SlCS, while other 51 patients ( 65 eyes ) in group Phaco were treated by phacoemulsification. And then, postoperative visual acuity, corneal astigmatism, surgically induced astigmatism ( SlA ) and intraoperative and postoperative complications were contrasted between groups.
?RESULTS: After 1d and 1wk of postoperation, there were 38 eyes ( 64. 4%) and 41 eyes ( 69. 5%) having a better visual acuity of 0. 5 in the SlCS group, while there were 29 eyes (44. 6%) and 32 eyes (49. 2%) in the Phaco group. The vision of SlCS group was better than that of Phcao group (χ2 = 4. 877, 5. 242, P < 0. 05 ). On postoperative 1 and 3mo, with acuity of 0. 5 or better, eye numbers showed no statistically significant differences between two groups (χ2 = 0. 005, 0. 085, P>0. 05). The average corneal astigmatism used analysis of repeatedly measuring designing variance: Comparing the corneal astigmatism in intra - groups at different times, it was statistically significant (F=25. 624, P<0. 05), and had a tendency to decrease with time. However, there was no statistical significance for corneal astigmatism between groups (F=0. 986, P>0. 05). The coneal astigmatism of each group was higher at 1wk after the surgery than that of preoperation, and the contrast had statistical sigenficence (t=2. 906, 2. 427, P<0. 05). The Phaco group with SlA was lower than the SlCS group at 1wk and 1mo after the surgery (t=-4. 628, 2. 770, P<005). lt had no statistical significance in SlA by comparing with the two groups at 3mo after the surgery (t=0. 754, P>0. 05). There were statistical differences in SlA at different time both by intra-group comparison and group comparison ( F=26. 37, P<0. 05, F = 14. 29, P<0. 05). The comparison of posterior capsule rupture, the postoperative corneal edema and anterior chamber pigment membrane reaction in two groups showed no statistical significance.
?CONCLUSlON: Our research shows that small-incision cataract surgery and phacoemulsification had similar effect in the treatment of cataract. Phacoemulsification is not the only surgery option for the best treatment effect. Small- incision cataract surgery can be popularized in basic- level hospitals, achieving the effect similar to phacoemulsification.
