Treating Presbyopia and Deposits in Regular Corneas with Tangible Hydra-PEG Coated Scleral Lenses

We are excited to share a guest post from Dr. Andrew J. Biondo, O.D., F.S.L.S., from Kirkwood Eye Associates in Kirkwood, Missouri. Dr. Biondo shared this case study as part of a webinar series educating eye care professionals about Tangible® Hydra-PEG® custom contact lens coating to improve comfort, wear time and overall patient acceptance with specialty contact lens designs.

Dr. Biondo feels that scleral lenses can be very useful in treating presbyopic patients and can offer benefits over soft multifocal and corneal GP multifocal lenses.

Case Summary:

One of his patients had transitioned from reading glasses to soft multifocal contacts but had issues with night driving, distance vision and reduced wear time. She wanted to stay in contacts but wanted a better solution.

A multifocal scleral lens was prescribed, and while it fit well, the patient showed surface deposits and variable wettability that impacted vision from time to time. The lenses were re-ordered with the same parameters but with Tangible Hydra-PEG coating added.

At the second follow-up, the patient reported superb all-day comfort but with much more consistent vision at all distances, and the ocular surface showed a uniform tear layer.

In summary, for this patient, comfort was immediately improved in the scleral lens as compared to her soft lenses, but the vision didn’t reach its maximum potential until the tear film consistency and distribution was improved with the Tangible Hydra-PEG coating.  The coating, which can last for a full year, is great for multifocal scleral lens patients because the precise optics of these lenses are heavily dependent on a healthy and consistent tear film.

Thank you, Dr. Biondo, for sharing your experience and insights!
