AlM:To observe the clinical effect of 2. 2mm micro-incision phacoemulsification ( Phaco ) combined intraocular lens( lOL) implantation in the eyes with short axial length and compared with traditional 3. 0mm incision phacoemulsification operation for clinical work and research objective information.METHODS:ln this prospective clinical control study, 60 cases (60 eyes) with cataract performed 2. 2mm micro-incision phacoemulsification combined lOL implantation ( micro-incision group, implanted Akreos Ml60 lOL ) and 3. 0mm incision phacoemulsification operation ( small incision group, implanted Akreos Adapt lOL ) , whose axial length ranged 17. 68 ~ 21. 32mm, average 20. 35 ± 0. 61mm. Average axiall ength respectively of two groups:20.57±0.39mm and 20.21±0.52mm. Effect Phaco time ( EPT ) and average ultrasonic energy ( AVE ) were recorded. The best corrected visual acuity ( BCVA ) , intraocular pressure ( lOP ) , anterior chamber depth ( ACD) , corneal endothelial cell density and the operative complications were observed postoperatively. All cases were followed up at 1, 7, 30 and 90d after operation.RESULTS:EPT and AVE between two groups had no statistical significance(P>0. 05). At the 1, 7 and 30d after surgery, induced astigmatism ( SlA ) of micro-incision group was lower than that of small-incision group. SlA between two groups had statistically significant ( P <0. 05), but in the 90d SlA between two groups had no statistical significance(P>0. 05). At the 7d, the BCVA between two groups had statistical significance(P<0. 05), but at the 30 and 90d, BCVA between two groups had no statistical significance(P>0. 05). At the 7, 30 and 90d, corneal endothelial cell density of micro-incision group was higher than that of small incision group. Corneal endothelial cell density between two groups had no statistical significance. The mean ACD was significant increased postoperatively than preoperatively and had no statistical significance ( P>0. 05 ) . The anterior chamber stabilized during the operation. There was not incision hot harmed during operation and postoperation.CONCLUSlON:Compared with 2. 2mm micro-incision and traditional 3. 0mm incision phacoemulsification, two groups have the same safety and 2. 2mm micro-incision phacoemulsification has small SlA, organization small harm and improved visual acuity in early stage.关键词
