To report early experience with a posterior chamber precrystalline intraocular lens designed for correction of severe myopia from -10 to -30 diopters. This intraocular lens respects the transparent crystalline lens and does not interfere with accommodation.
The concave-convex methylmethacrylate lens, with flexible haptics that are supported in the sulcus, is placed behind the iris, in front of the lens, and centered with the pupil.
From July 1995 to November 1998, 149 precrystalline lenses have been inserted with few, generally reversible complications, which are now largely prevented by adequate modification of the intraocular lens. Correction has been satisfactory and stable.
Although follow-up is relatively short, precrystalline lens placement may be considered an important contribution to the surgical management of severe myopia to improve the patient's vision and, consequently, quality of life.
报告一种用于矫正-10至-30屈光度重度近视的后房型预晶状体人工晶状体的早期使用经验。这种人工晶状体保留透明晶状体,不干扰调节功能。
采用凹凸型甲基丙烯酸甲酯晶状体,其具有柔性襻,襻支撑在睫状沟内,将晶状体置于虹膜后方、晶状体前方,并与瞳孔中心对齐。
1995年7月至1998年11月,共植入了149枚预晶状体,并发症较少,且大多为可逆性,目前通过对人工晶状体进行适当改进,很大程度上可预防并发症。矫正效果令人满意且稳定。
尽管随访时间相对较短,但预晶状体植入术可被视为对重度近视手术治疗的一项重要贡献,有助于改善患者视力,进而提高生活质量。
