Abstract | Full Text

AIM: To compare the postoperative vision performance of multifocal intraocular lens implantation combined with corneal incision to correct astigmatism and that of monofocal intraocular lenses implantation.<p>METHODS: Eighty patients(100 eyes)with age-related cataract and low cornea astigmatism were divided into control group and intervention group. Intervention group received limbal relaxing incisions at the steepest meridian axis during phacoemulsification with temporal corneal incision and implanting multifocal intraocular; the control group only received phacoemulsifieation with temporal corneal incision and implanting monofocal intraocular lenses. Uncorrected distance visual acuity(UCDVA), uncorrected near visual acuity(UCNVA)and cornea astigmatism were observed 1 week, 1 month and 3 months postoperatively. Best corrected near visual acuity(BCNVA), best corrected distance visual acuity(BCDVA), distant corrected near visual acuity(DCNVA), were observed 3 months postoperatively. <p>RESULTS: UCDVA and UCNVA in intervention group were higher than that in control group 1 week, 1 month and 3 months postoperatively while the cornea astigmatism in intervention group was lower than that in control group. BCNVA, BCDVA and DCNVA in both groups showed obvious improvement 3d after the surgery. There was no significant difference between the two groups in UCDVA and UCNVA 1 week, 1 month and 3 months postoperatively and in BCDVA and BCNVA 3 months postoperatively.<p>CONCLUSION:Multifocal intraocular lens implantation combined with transparency cornea relaxing incisions can effectively rectify preoperative cornea astigmatism in cataract patients, and it can provide good visual acuity of entire range, thus to extend the target users of multifocal intraocular lens.
