Study shows successful vision correction with GP lenses

Researchers successfully fit gas permeable contact lenses in patients with both therapeutic and vision correction needs.
The retrospective study included 232 subjects who began a fitting procedure for any type of contact lens; 71.6% were for refractive prescriptions and 28.4% were for therapeutic prescriptions. About one-third of patients (34.4%) had never worn any type of contact lens.
Sixty-one of the 88 subjects who were fitted with gas permeable (GP) diagnostic lenses were successful in that they comfortably wore the GP and showed an optimal ocular surface physiology.
Of the remaining 27 subjects, four were finally fit with silicone hydrogels, 14 were fit with hydrogels, and nine were unsuccessful in all contact lens types.
In therapeutic prescriptions, GP lenses were the first trial lens option chosen in 61 cases; 42 of these had an irregular cornea, and 19 were fit for orthokeratology.
Fifty-nine subjects obtained a successful fitting with comfortable GP wear and optimal ocular surface physiology.
“In many practices, GP lenses have a limited role in refractive fittings, and this type of lens is not considered the first choice option in healthy patients for correcting refractive errors,” the researchers wrote.
This study improves the information that can be provided to patients at the beginning of the contact lens fitting process, researchers concluded. – by Abigail Sutton
