AI Technical Summary
Technical Problem
Existing methods for coating intraocular lenses to reduce self-tackiness are inefficient, time-consuming, and prone to lens damage, with potential for incomplete coatings and adverse optical effects.
Method used
The use of spatial atomic layer deposition (s-ALD) to apply a thin, uniform coating to intraocular lenses while they are still in their formation device, utilizing a system with inert gas, precursor, and plasma sources to achieve a controlled and consistent coating thickness.
Benefits of technology
This method reduces self-tackiness and improves unfold time consistency, minimizes lens handling, and maintains optical performance by applying a thin, uniform coating that is chemically bonded to the substrate.
