A Study was conducted to report indications for wear, visual outcomes, and complications of EyePrintPRO (EPP) scleral contact lens (SCL) use.

All patients who were fitted with this system were found via a retrospective examination. We defined baseline demographics, wear indications, and contact lens history. At both the baseline and follow-up, habitual-corrected visual acuity was assessed. The researchers kept track of adverse wear symptoms and signs, reprinting, and product discontinuation.

Results:
--95 eyes from 69 patients were followed for a median of 12.1 months (interquartile range 4.4–19.6).

--Indications for wear included vision improvement and/or ocular surface stabilization in the setting of irregular corneal shape (72%), ocular surface disease (18%), exposure keratopathy (7%), neurotrophic keratitis (5%), and extracorneal topographical abnormalities preventing noncustom lens fitting such as glaucoma drainage devices (8%).

--Median habitual-corrected visual acuity improved from 0.67 to 0.08. One-third of eyes developed adverse wear symptoms.

--16% eyes developed adverse wear signs. Device cessation occurred in 10 eyes and reprinting occurred in 14 eyes unrelated to prior lens wear or indication (P = 0.67 and 0.15, respectively).

--In eyes that previously failed SCLs (n = 56), 12 eyes required reprinting and 49 eyes continued use.

In conclusion, irregular corneal shape, ocular surface disease, and extracorneal topographic anomalies are all indications for EPP use. The use of EPP increases visual acuity. Clinicians and patients should be mindful of the risks of EPP use, including adverse wear symptoms/signs and system discontinuation. In eyes that have previously failed SCLs, EPP is a viable salvage treatment.
