Abstract

AIMS

To investigate the adhesion characteristics of several intraocular lenses (IOLs) to the simulated and rabbit lens capsule.

METHODS

Adhesive force to bovine collagen sheets was measured in water with polymethylmethacrylate (PMMA), three piece silicone, and acrylic foldable IOLs. In rabbit eyes, phacoemulsification and IOL implantation were performed. Three weeks later, adhesion between the anterior/posterior capsules and IOL optic was tested, and the capsule was examined histologically.

RESULTS

The mean adhesive force to the collagen sheet was 1697 (SD 286) mg for acrylic foldable, 583 (49) mg for PMMA, and 0 mg for silicone IOLs (p = 0.0003, Kruskal-Wallis test). Scores (0-5) of adhesion between rabbit anterior capsule and IOL optic were 4.50 (0.55) for acrylic foldable, 3.20 (0.84) for PMMA, and 0.40 (0.55) for silicone IOLs (p = 0.004). Scores between rabbit posterior capsule and IOL optic displayed a similar tendency; 4.50 (0.84) for acrylic foldable, 3.00 (1.00) for PMMA, and 0.40 (0.55) for silicone IOLs (p = 0.021). Histological observation indicated that the edge of IOL optic suppressed the migration of lens epithelial cells towards the centre of the posterior capsule. This inhibitory effect was most pronounced with acrylic foldable IOL and least with silicone IOL.

CONCLUSIONS

The acrylic foldable IOL adhered to the lens capsule more than the PMMA IOL, and the silicone IOL showed no adhesiveness. These differences seem to play a role in preventing lens epithelial cells from migrating and forming posterior capsule opacification.

摘要

目的

研究几种人工晶状体(IOL)与模拟及兔晶状体囊膜的黏附特性。

方法

在水中测量聚甲基丙烯酸甲酯(PMMA)、三片式硅胶和丙烯酸可折叠IOL对牛胶原片的黏附力。在兔眼中进行超声乳化和IOL植入。三周后,测试前/后囊膜与IOL光学部之间的黏附情况,并对囊膜进行组织学检查。

结果

丙烯酸可折叠IOL对胶原片的平均黏附力为1697(标准差286)mg,PMMA为583(49)mg,硅胶IOL为0 mg(p = 0.0003,Kruskal-Wallis检验)。兔前囊膜与IOL光学部之间的黏附评分(0 - 5分),丙烯酸可折叠IOL为4.50(0.55),PMMA为3.20(0.84),硅胶IOL为0.40(0.55)(p = 0.004)。兔后囊膜与IOL光学部之间的评分呈现类似趋势;丙烯酸可折叠IOL为4.50(0.84),PMMA为3.00(1.00),硅胶IOL为0.40(0.55)(p = 0.021)。组织学观察表明,IOL光学部边缘抑制了晶状体上皮细胞向后囊膜中心的迁移。这种抑制作用在丙烯酸可折叠IOL中最为明显,在硅胶IOL中最不明显。

结论

丙烯酸可折叠IOL比PMMA IOL更易黏附于晶状体囊膜,而硅胶IOL无黏附性。这些差异似乎在防止晶状体上皮细胞迁移和形成后囊膜混浊中起作用。
