Popis: AIM:To observe the post-operative outcomes, safety and complications of the sutureless-intrascleral fixation of posterior chamber intraocular lens(SF-PCIOL)by using the modified Yamane's technique.METHODS:This study involved 5 patients who underwent SF-PCIOL with the modified Yamane's technique, from December 2017 to September 2018. The longest follow-up time was 12mo, and the primary outcomes included uncorrected visual acuity(UCVA, LogAMR)and bestcorrected visual acuity(BCVA, LogMAR), intraocular pressure and the location and stability of IOLs.RESULTS: The BCVA of 3 patients were ranged from 0.0 to 0.1 by the time of following up 12mo postoperatively. The difference between the spherical equivalent refraction and the predicted spherical equivalent refraction was in a range of 0.11-0.62 diopters. In the other two cases, at 3mo after the surgery, the UCVA was 0.2 for one case, and the BCVA was the same as preoperative corrected visual acuity for another case, where the patient manifested corneal leucoma and macular edema prior to surgery. During the follow-up period, the flanges and the IOL haptics of all the recruited patients were maintained in an ideal position, the optics were located in center of the pupils, and no visible IOL decentration or tilt was observed. Neither hypotony nor other complications were discovered in all the cases.CONCLUSION: For SF-PCIOL by using modified Yamane's technique, smaller incisions and shorter operation time are feasible, and the need for scleral flaps, sutures and fibrin glue is eliminated. The IOLs are well centered and fixed securely. A learning curve is necessary to master this surgery technique. As revealed by our initial observation, the surgery is capable of producing satisfactory and consistent postoperative outcomes for patients with fewer postoperative complications as long as the crucial points are fully understood.
