Adhesion study of cultured human lens capsule cells on hydrophilic intraocular lenses coated with polyethylene glycol
| Summary: | PURPOSE: To evaluate the adhesion of human lens capsule cells on hydrophilic acrylic intraocular lenses (IOLs) coated with polyethylene glycol (PEG). SETTING: Department of Ophthalmology, Faculty of Medicine, Universidade Estadual Paulista Botucatu, Sao Paulo, Brazil. DESIGN: Experimental study. METHODS: Human anterior lens capsules obtained during cataract surgery were cultured and seeded (200 cells/IOLs) in triplicates on the surface of a copolymer comprising hydroxyethyl methacrylate, ethyl methacrylate, and methyl methacrylate IOLs (Loflex) treated or not treated with PEG. After 26 hours, the number of viable adherent cells was estimated by counting in a hemocytometer. RESULTS: The coating of hydrophilic acrylic IOLs with PEG was effective in inhibiting cell adhesion (P < .05). Cells showing 2 distinct morphologic patterns epithelial and dendritic-like-were observed during the in vitro establishment of the cultures. A tendency toward greater adhesion of dendritic-like cells was observed in untreated IOLs compared with treated IOLs (P = .095). CONCLUSION: Coating hydrophilic acrylic IOLs with PEG was effective in inhibiting cell adhesion. This treatment might play a role in posterior capsule opacification prevention. (C) ASCRS and ESCRS |
