巩膜固定法植入后房型人工晶体

Scleral Fixation Technique of Posterior Chamber Intraocular Lens Implants

对16例无后囊膜支持病例,用巩膜固定技术,植入后房型人工晶体。全部病例平均追踪10.6月(最短4月,最长20月)。16眼中有6眼矫正视力达1.0以上,4眼视力为0.6～0.9,4眼视力0.3～0.5,另两眼视力为0.1～0.2,无严重并发症如人工晶体脱位、青光眼、网膜脱离、迟发性囊样黄斑水肿等。结果表明本技术安全有效有前途,但仍需持续观察,对长期效果作出评价。

Using a technique of scleral fixation, we have sutured posterior chamber intraocular lenses to ciliary sulcus. The procedure was carried out in sixteen eyes without capsular support. All the cases were followed up for a minimum of four months (range, four to twenty months; mean 10.6 months). At the end of the follow up, six eyes had a best corrected visual acuity of more than 1.0, four eyes 0.6—0.9 and four eyes 0.3-0.5. Two eyes 0.1—0.2. There are no severe complications, such as decentration of the lens, glaucoma, retinal detachment, delayed cystoid edema, etc. It is suggrsted that the technique is safe, effective, and promising. However, the long-term results must be carefully assessed.
