A 10 mm overall diameter one-piece compressible-disc lens was developed for in the bag implantation after cataract surgery performed by envelop technique or by phacoemulsification. The lens consists of an outer ring connected to a 6 mm diameter optical zone by two compressible loops. The loops and the outer ring are 10 degrees angulated with respect to the optic. The lens can be implanted through a 6 mm tunnel incision and a 5 mm diameter capsulorrhexis. In cadaver eyes, this lens was found to fit snugly in the capsular bag after implantation, leaving no room for decentration. The lens is also suitable for implantation in cases of anterior capsule radial tears. When sectorial zonulolysis is present, the introduction of this lens into the capsular bag stretches the detached bag to the periphery, thus facilitating the lens implantation.
研发了一种总直径为10毫米的一体式可压缩盘状晶状体,用于囊袋内植入,适用于采用囊膜技术或超声乳化白内障手术后的情况。该晶状体由一个外环组成,外环通过两个可压缩环与直径为6毫米的光学区相连。这些环和外环相对于光学部呈10度角。该晶状体可通过一个6毫米的隧道切口和一个直径5毫米的撕囊口植入。在尸体眼中,发现该晶状体植入后能紧密贴合在囊袋内,没有偏心的空间。该晶状体也适用于前囊膜放射状撕裂的情况。当存在扇形悬韧带溶解时,将该晶状体引入囊袋会将分离的囊袋拉伸至周边,从而便于晶状体植入。
