Clinical observation on transscleral sutured fixation intraocular lens implanted in the capsular bag for subluxated lens / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To investigate the clinical effect of transscleral sutured fixation intraocular lens(IOL)implanted in the capsular bag combined with phacoemulsification for subluxated lens(SL). <p>METHODS: A prospective study of 18 consecutive cases(18 eyes)with SL(≤270°)was treated with phacoemulsification by Nagahara's chop method combined with the iris hook. Then according to the extent of SL, one or two IOL haptics were transscleral sutured suspension in the capsular bag. Moreover, two cases were performed 25G minimal invasive vitrectomy. The clinical efficacy was observed such as visual acuity, best corrected visual acuity(BCVA), intraocular pressure(IOP), the position of IOL and complications.<p>RESULTS: All cases were performed successfully. With following-up ranged from 6-12mo, the BCVA was improved obviously, which had significant difference contrasted to that of preoperation(<i>t</i>=7.30, <i>P</i><0.01). All cases' IOP ≤21mmHg, the position of IOL were normal without dislocation. No several complications took pace in intraoperative or postoperative surgical process.<p>CONCLUSION: Without implanting capsular tension ring(CTR), IOL in the capsular bag sutured fixation by one or two haptics suspension is an alterative approach for SL. This method maintains the position of IOL and rehabilitates visual acuity, and obviates CTR dislocation. So this way is effective and economical to be accepted by some basic hospital.
