Prosthetic scleral lens improves vision in ocular disease

The therapeutic EyePrintPRO scleral lens offers improvement in a variety of eye diseases, including limbal stem cell deficiency, post-PRK decentered ablation and pellucid marginal degeneration, according to researchers in the Canadian Journal of Ophthalmology.

Common complications with scleral lens wear, such as bulbar redness, conjunctival blanching or impingement and scleral lens adhesion, were reduced or eliminated in the retrospective case series with the EyePrintPRO lens.

In the review, 14 eyes of 10 patients were fitted with the EyePrintPRO therapeutic scleral lens, with 12 months of wear for the average duration.

Patients had limbal stem cell deficiency, post-photorefractive keratectomy (PRK) decentred ablation, pellucid marginal degeneration, Stevens-Johnson syndrome, keratoconus, dry eye, neurotrophic keratitis, exposure keratitis from facial nerve paralysis and/or post-radial keratotomy symptoms.

Mean best-corrected visual acuity was 20/36, and after the fitting BCVA was 20/21. Nine patients reported resolution of blurry vision, and all reported improvement in dry eye, redness and pain symptoms. Six of seven previous lens wearers reported significantly greater comfort with EyePrintPRO wear and the ability to wear the lens throughout the day, according to researchers.

EyePrintPRO is a prosthetic scleral cover shell that improves vision by creating a new, smooth, refractive surface for the eye, according to a company press release. Elevation Specific Technology is used to match the unique irregularities of each individual eye.

An EyePrint Impression captures the precise curvatures of the entire ocular surface. Doctors then send the resulting impression to an EyePrint lab for 3-D scanning. Next, the scanned data is fed to a “numerically controlled machining system to produce a lens that matches the impression exactly and, therefore, fits the individual cornea and sclera perfectly,” according to the release.

The EyePrint is entirely individual, like a fingerprint, Christine Sindt, OD, FAAO, FSLS, EyePrintPRO developer and clinical professor of ophthalmology and visual sciences at University of Iowa, said in the release.
