Patients with presbyopia treated with laser scleral microporation experienced up to a three times increase in their binocular visual field, according to a poster at the virtual Women in Ophthalmology Summer Symposium. Hipsley and colleagues evaluated changes in visual outcomes of 32 presbyopic eyes of 16 patients who underwent laser scleral microporation (Ace Vision Group) performed with an Er:YAG laser. The laser creates a microporation in four quadrants of a 5 mm by 5 mm matrix in five anatomic zones, which uncross-links aged scleral microfibrils over the area of the ciliary muscles.

Patients gained a mean logMAR visual acuity of 0.21 at near and intermediate at 3 months. In the early results of five patients, the average area of binocular summation increased to 104.68 mm2 from 70.45 mm2 at baseline. Some patients experienced up to a three times increase in their binocular visual field at 1 month.

Preliminary results of the technology show it to be a safe and effective procedure for restoring all ranges of vision, according to the poster.

“Whereas extended depth of focus aims to impact a patient’s depth of focus through an IOL replacement of a cataract patient’s natural lens, [laser scleral microporation] therapy restores dynamic clear vision to the presbyopic patient by impacting all optical elements to restore visual functionality without replacing it,” Hipsley
