GP scleral lens improves visual acuity, comfortable wear time in irregular corneas

Visual acuity and patient satisfaction improved in patients with irregular corneas after wearing scleral contact lenses for 1 month.

Researchers analyzed 15 eyes of 15 patients who did not tolerate gas permeable corneal contact lenses and were fitted with scleral contact lenses (Rose K2 XL).

Visual acuity and patient satisfaction was assessed with the previous optical correction and 1 month after the Rose K2 XL (Menicon) lenses were fit.

Mean best corrected visual acuity before fitting the Rose K2 XL lenses was 0.31 logMAR, which represents the best visual acuity with their corneal GP contact lenses. After 1 month of using the Rose K2 XL lenses patients achieved a BCVA of 0.06 logMAR. Researchers found this difference statistically significant.

They added that the BCVA improved in all patients, with a fivefold improvement compared with the measurement before the Rose K2 XL lenses were fit.

After 1 month of wearing the new lenses, the length of comfortable wear reached a mean of 9.33 hours, ranging from 6 hours to 12 hours.

Patients who never tolerated contact lenses showed the shortest comfortable wear times.

The mean visual function index score before fitting the scleral lenses was 72.74 and 1 month after fitting the Rose K2 XL lenses it rose to 89.31, which was also statistically significant, according to researchers.

Future research should focus on “larger numbers of patients and different types of GP scleral lenses to confirm the benefits and determine whether certain designs and/or materials are associated with better tolerance and visual function,” the researchers wrote. – by Abigail Sutton
