Extended wear contact lenses for aphakia

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• Unilateral aphakia correction traditionally involves daily contact lenses or intraocular lenses.
• The need for improved and convenient aphakia management solutions persists.

Purpose of the Study:

• To investigate the efficacy and suitability of the Cooper Permalens soft contact lens as an extended wear option for unilateral aphakia.
• To assess the performance of extended wear contact lenses in terms of patient fit, visual outcomes, and complication rates.

Main Methods:

• A cohort of 177 eyes with unilateral aphakia were fitted with Cooper Permalens soft contact lenses for extended wear.
• Data collection focused on lens fit, visual acuity, visual function, and the incidence of contact lens-related problems.

Main Results:

• The Cooper Permalens demonstrated potential as an extended wear contact lens for aphakia correction.
• Analysis included detailed assessments of lens fit, visual performance, and identification of common contact lens-related issues.

Conclusions:

• Extended wear soft contact lenses, such as the Cooper Permalens, present a viable option for managing unilateral aphakia.
• Further evaluation of fit, visual function, and management of complications is crucial for optimizing this modality.
