Effect of different focal intraocular lens implantation in cataract surgery

Abstract:

AIM:To explore the effect of the cataract patients after cataract surgery by the treatment of different focal intraocular lens implantation.

METHODS: A total of 65 cases of cataract patients who received treatment in our hospital were selected. According to the different division of implanted crystal, 32 cases(43 eyes)of multifocal intraocular lens were selected as the observation group, 33 cases(47 eyes)with monofocal intraocular lens were selected as the control group. We compared distant and near visual acuity in two groups who received operations after 1 and 3mo. We analyzed the contrast sensitivity values and the results of questionnaire in two groups.

RESULTS: The values of UDVA, CDVA, UNVA and CNVA in the observation group were higher than those in the control group at 3mo after operation(P<0.05); the space frequency detection sensitivity in the observation group received surgery after 3mo was significantly better than that of the control group in 3, 6, 12 and 18c/d whether glare or not, the difference was statistically significant(P<0.05); the two groups of patients who received the operation after 3mo were investigated, there were no differences in factor of nocturnal disorders and dizziness in the glare(P>0.05). We compared different of the night action disorder and glare dizziness in two groups of patients, the difference was no statistical difference(P>0.05). And overall satisfaction in the observation group was significantly higher than the control group(P<0.05).

CONCLUSION: Postoperative visual acuity of the patients who used multifocal intraocular lens is better, and contrast sensitivity have increased, the overall satisfaction is high, it can meet the visual life needs of patients.
