What contact lens material was developed in 1979 by Syntex Ophthalmics?

The correct answer is Silicone-Acrylate, which was developed in 1979 by Syntex Ophthalmics. This material represented a significant advancement in contact lens technology because it combines the desirable properties of both silicone and acrylate. Silicone materials contribute to improved oxygen permeability, which is crucial for maintaining corneal health during contact lens wear. This increased oxygen transmission helps to reduce the risk of complications such as hypoxia, which can occur with lenses made from materials that do not allow sufficient oxygen to reach the cornea.

In addition to enhanced oxygen permeability, the addition of acrylate provides better wettability and comfort. This makes Silicone-Acrylate an ideal choice for soft contact lenses since it balances the need for both comfort and eye health. This development ultimately paved the way for the evolution of modern soft contact lenses and contributed to the widespread adoption of contact lens wear.

Understanding the development of materials like Silicone-Acrylate is essential for practitioners, as it highlights the continuous improvement in contact lens technologies aimed at enhancing the wearer's comfort and ocular health.
