Abstract
METHODS: This study included 80 cases of cataract patients(88 sicked eyes)treated in our hospital from January 2016 to January 2017. All patients underwent phacoemulsification combining with intraocular lens implantation for treatment. Based on the review of treatment, 40 cases(43 sicked eyes)receiving femtosecond laser assisted cataract surgery were included into the observation group, 40 cases(45 sicked eyes)receiving conventional phacoemulsification only were divided into the control group. The proportion of patients whose postoperative uncorrected visual acuity >0.5 of the two groups were compared, and sac diameter, capsule size, intraoperative cumulative energy release(CDE)were recorded, the corneal endothelial cell density and variation were recorded before and after operation, the preoperative and postoperative ratio of hexagonal cells were compared between the two groups subsequently.
RESULTS: At 1d postoperatively, uncorrected visual acuity >0.5 of the observation group was no significant difference with that of the control group; the ratio was 74% at 6mo after surgery, which was significantly higher than that of the control group(53%), there was statistical significance(P<0.05). The diameter of the anterior capsulotomy, the size of the capsule, the grade II nuclear CDE, and the grade III nuclear CDE of the observation group were sharply different from those of the control group, there was statistical significance(P<0.05). The differences of corneal endothelial cell density and variation, proportion of hexagonal cells before and after surgery of the two groups were significant, and the difference after 6mo between the two groups was huge, there was statistical meaning(P<0.05).
CONCLUSION: Femtosecond laser assisted cataract surgery can reduce the effect of ultrasound energy on cornea, and can sharply decrease the damage to corneal endothelial cell morphology and function.
