Complications associated with spin-cast soft contact lenses

Area of Science:

• Ophthalmology
• Biomaterials Science

Background:

• The Bausch & Lomb Soflens represents the sole spin-cast soft contact lens produced in the United States.
• Spin-cast manufacturing offers a distinct production method for soft contact lenses.

Purpose of the Study:

• To evaluate the complication profile of the Bausch & Lomb Soflens, the only spin-cast soft contact lens manufactured in the US.
• To compare the complication rates of spin-cast lenses with traditional lathe-cut hydrophilic lenses.

Main Methods:

• Review of clinical data and reported complications associated with the Bausch & Lomb Soflens.
• Comparative analysis of complication types between spin-cast and lathe-cut soft contact lens modalities.

Main Results:

• No significant complications have been specifically reported for the Bausch & Lomb Soflens.
• The observed complications with spin-cast lenses mirror those typically seen with lathe-cut hydrophilic lenses.
• The most frequent complications identified are poor lens centering and the accumulation of lens deposits.

Conclusions:

• The Bausch & Lomb Soflens demonstrates a favorable safety profile, comparable to established lathe-cut lens technologies.
• Lens centering and deposit formation are key areas for monitoring in both spin-cast and lathe-cut soft contact lens wear.
• Further research may explore strategies to mitigate centering issues and deposit adhesion in spin-cast contact lens designs.
