Fabrication of Hydrophilic Surface on Rigid Gas Permeable Contact Lenses to Enhance the Wettability Using Ultraviolet Laser System

open access: yesMicromachines, 2019
The widely used rigid gas permeable (RGP) contact lenses provide higher oxygen permeability and tear exchange rate than do soft contact lenses. However, their wettability warrants improvement to enhance the wearing comfort.

True Story of Poly(2-Hydroxyethyl Methacrylate)-Based Contact Lenses: How Did It Really Happen

open access: yesSubstantia, 2022
Soft hydrogel contact lenses represent the most famous and commercially successful application of poly(2‑hydroxyethyl methacrylate). The scarcely crosslinked network of this hydrophilic polymer finds its use also in many other fields, be it in (bio ...

Hybrid contact lenses for the correction of primary and induced ametropias

open access: yesРоссийский офтальмологический журнал, 2020
The review presents the data on the use of hybrid contact lenses (HCL), a modern method of contact correction of ametropias of diverse origins. A HCL has a central rigid optical zone made of highly gas-permeable material and a flexible peripheral part ...

Towards improving the biocompatibility of prosthetic eyes

open access: yesHeliyon, 2021
Prosthetic eyes are currently manufactured using Poly(methyl methacrylate) (PMMA) which is not an ideal material because it is hydrophobic. While significant research has investigated the benefits of hydrophilic materials for contact lenses, no such ...

Hydrogel Contact Lens for Extended Delivery of Ophthalmic Drugs

open access: yesInternational Journal of Polymer Science, 2011
Soft contact lenses can improve the bioavailability and prolong the residence time of drugs and, therefore, are ideal drug carriers for ophthalmic drug delivery. Hydrogels are the leading materials of soft contact lenses because of their biocompatibility
