A novel method of fitting scleral high resolution optical coherence lenses using tomography

Purpose. Case report study of a novel method of fitting large rigid gas-permeable lenses (cornea-scleral, mini-scleral, scleral). Methods. Nine patients with different corneal and refractive conditions were fitted with scleral-type rigid gas-permeable lenses using high resolution ocular coherence tomography. All patients achieved excellent visual acuity and comfort. Lenses were well tolerated without significant complications. Three cases are discussed in detail. Two of the 3 patients had previously undergone fitting with trial lenses so that the different methods could be compared with respect to number of lenses used to achieve a final fit. Conclusions. High resolution biometry proved to be a highly useful fitting tool and seems to offer a more accurate and efficient alternative to fitting scleral-type lenses compared with the trial lens method.
