Comparison of tilt and decentration of two aspheric intraocular lens by ultrasonic biomicroscope
AIM: To compare the differences of tilt and decentration of two aspheric posterior chamber intraocular lens(PC-IOL)implantation by ultrasonic biomicroscope(UBM). <p>METHODS:Thirty-seven patients(45 eyes)underwent cataract surgery were distributed to two groups randomly. Group A was implanted w...

| description | AIM: To compare the differences of tilt and decentration of two aspheric posterior chamber intraocular lens(PC-IOL)implantation by ultrasonic biomicroscope(UBM). <p>METHODS:Thirty-seven patients(45 eyes)underwent cataract surgery were distributed to two groups randomly. Group A was implanted with Akreos AO(Bausch & Lomb; four-haptic)while group B implanted with ZCB00(Abbott Medical Optics, Inc. AMO; two-haptic). All eyes underwent standard phacoemulsification with intraocular lens implantation. Diameter of capsulotomy was recorded. One month postoperatively, vision, best-corrected visual acuity(BCVA)assessment, slit lamp examination, and anterior chamber depth(ACD)measured by UBM were performed. Tilt and decentration were measured horizontally and vertically, and total tilt and decentration were calculated by geometry method.<p>RESULTS:No statistical difference was found in BCVA and diameter of capsulotomy between two groups(<i>P</i>>0.05). The mean ACD of group A and group B were 3.86mm±0.31mm and 4.14mm±0.31mm respectively, which showed it had statistically significant difference(<i>P</i><0.05). Horizontal decentration, vertical decentration and total decentration of group A were 0.15mm±0.09mm, 0.15mm±0.12mm and 0.22mm±0.12mm respectively, while it were 0.22mm±0.21mm, 0.14mm±0.15mm, 0.29mm±0.22mm for group B. Horizontal tilt, vertical tilt and total tilt of group A were 0.63°±0.62°, 0.89°±0.85°and 1.22°±0.76°, while it were 1.36°±1.48°, 1.46°±1.62° and 2.21°±1.97° for group B. No statistically significance was found in tilt and decentration between group A and group B, no matter horizontally or vertically or totally(<i>P</i>>0.05). <p>CONCLUSION:Two-haptic IOL shows no difference in tilt and decentration with four-haptic IOL postoperatively. |
