Experience with extended wear hydrogel lenses for aphakia

Area of Science:

• Ophthalmology
• Biomaterials Science

Background:

• Aphakia, the absence of the eye's natural lens, presents significant visual challenges.
• Contact lens correction is crucial for restoring vision in aphakic patients.
• Previous contact lens options have shown limited success or tolerance in some aphakic individuals.

Purpose of the Study:

• To evaluate the efficacy and patient acceptance of hydrogel soft contact lenses in aphakic eyes.
• To assess the long-term wearability and visual outcomes with hydrogel lenses in a challenging patient population.

Main Methods:

• A cohort of 23 aphakic eyes was fitted with hydrogel soft lenses.
• Patients wore lenses for an average of 8.32 months (range: 3-14 months).
• Patient tolerance, visual acuity, and any complications were monitored.

Main Results:

• Nineteen out of 23 aphakic eyes successfully wore hydrogel soft lenses.
• Approximately 50% of patients had previously failed to tolerate other contact lens types.
• The primary complication was the development of surface deposits, necessitating lens care or replacement.
• All patients achieved satisfactory vision, with several using the lenses in their only functioning eye.

Conclusions:

• Hydrogel soft contact lenses are a well-tolerated and effective option for correcting aphakia, particularly for patients with a history of contact lens intolerance.
• Despite the challenge of surface deposits, hydrogel lenses offer a significant improvement in visual function and patient satisfaction for aphakic individuals.
