Prolonged wear soft contact lenses

|July 1, 1980
Summary
This study found that while prolonged wear soft contact lenses can be successfully fitted, they require significant office visits and lens replacements. Peripheral corneal ulceration was the most serious complication, but it did not cause permanent vision loss.
Area of Science:
- Ophthalmology
- Optometry
- Corneal Disease
Background:
- Soft contact lenses offer an alternative for vision correction.
- Prolonged wear contact lenses present unique fitting and management challenges.
Purpose of the Study:
- To evaluate the success rate, complications, and management requirements of prolonged wear soft contact lenses.
- To compare the resource utilization of soft contact lenses with intraocular lenses.
Main Methods:
- Prospective study of 78 eligible patients, with 50 successfully fitted and followed for 4 months to 4 years.
- Documentation of office visits, lens replacements, and complications.
Main Results:
- Successful fitting achieved in 65% of patients.
- Peripheral corneal ulceration occurred in 10% of patients, with no permanent visual loss.
- Uncomplicated cases required 6-7 office visits and at least one lens replacement per eye in the first year.
Conclusions:
- Prolonged wear soft contact lenses are a viable option when lens implants are contraindicated or as an alternative to secondary implantation.
- Management requires significant clinical resources, comparing unfavorably to intraocular lenses in terms of visits and replacements.
