Comparison Of Phaco And Sutureless Large-Incision Mannual Cataract Extraction In Hard Nuclues Cataract

Objective To compare the surgical outcome between phacoemulsification (PHACO) and sutureless large-incision manual cataract extraction (SLIMCE) in hard nucleus cataracts.Methods a total of 53 hard nuclear cataract patients (88eyes) were non-randomly divided into PHACO group with 28 patients (47eyes) and SLIMCE group with 25 patients (41 eyes). Visual acuity in consecutive 3 days postoperatively and at 1 week, corneal endothelial cell loss, corneal astigmatism and anterior segment were observed and compared in two groups.Results The uncorrected visual acuity in first 2 days postoperatively in SLIMCE group was better than PHACO group. There was no significant difference in two groups in corrected visual acuity at 1 week and in 1 month. Surgery induced corneal astigmatism in 1 month were 0.74±0.25D (PHACO), and 1.01±0.49D (SLIMCE)(P<0.05). The loss rate of corneal endothelial cell were 26% and 15% respectively in PHACO and SLIMCE group (P<0.05).Conclusion For the hard nucleus cataract, SLIMCE is faster than PHACO in visual acuity rehabilitation, fewer in corneal endothelial cell loss, but more obvious in surgery induced corneal astigmatism.
