| Abstract |
This study was planned considering the high-, medium-, low-water content materials to be used in the polymerization, while various additives with similar water contents were manufactured. For the preparation of hydrogel ophthalmic lens materials, based of hydrogel ophthalmic lens monomer used in the presence of HEA (hydroxyethyl acrylate), PVP (polyvinylpyrrolidone), NMV were used as additives for preparing the high-water content lens group, and HPMA (hydroxypropyl methacrylate) and BD were used for the medium-water content lens group. For the low-water content lens group, BMA (buthyl methacrylate), BDDA (1,4-butanediol diacrylate), and Bis-GMA (bisphenol A glycerolate diacrylate) were used, respectively, at about 10% ratios. The measurements of the contact angles, showed a different wettability value for each lens with a similar water content. And also, the lens curvature according to the change of time showed that the change amount became larger and the recovery time became longer from the lens samples with a lower water content to those with a higher water content. Based on this study, it can be concluded that wettability or other physical properties may be different even though it is a ophthalmic hydrogel lens having a similar water content. |
