Toric人工晶状体在合并高度角膜散光白内障中的应用
Toric intraocular lens for correction of high corneal astigmatism in cataract patients
摘要
Abstract
AIM:To evaluate the efficacy of Bi-Flex toric intraocular lens ( T-IOL ) ( Medicontur, Medical Engineering, Ltd. ,Inc. ) implantation to correct preexisting astigmatism in patients having cataract surgery.? METHODS: This retrospective consecutive study included 22 eyes of 16 patients with more than 2. 50 diopters ( D ) of corneal preexisting astigmatism having cataract. Preoperative and postoperative uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA ) , objective and subjective refraction and keratometric and topographic cylinder were measured. Postoperative the toric IOL axis was evaluated using vector analysis.? RESULTS: Postoperatively, subjective refractive cylinder was reduced significant ( P<0. 05 ) from 4. 05 ± 1. 53D to 1. 35 ± 0. 86D. The component J0 reduced in magnitude from -0.81±2.02D to -0.12±0.62D (P<0.05). Both, UCVA and BCVA improved significantly at 1mo after surgery (P<0. 05 in both cases). After the surgery, the UCVA and BCVA were 0. 24 ± 0. 19 and 0. 06 ± 0. 08, respectively. The mean toric IOL axis rotation was 2. 95 ± 5. 25 degree, with rotation less than 10 degrees in 86. 36％of eyes. No differences in mean keratometric values obtained before and after surgery were found (P>0. 05 for J0 and J45 ) .?CONCLUSION:Implantation of the Bi-Flex toric IOL is a safe and effective method to correct the preexisting regular astigmatism (greater than 2. 50D).关键词
