To evaluate changes in visual outcomes in presbyopic eyes after Laser Scleral Microporation (LSM).

An Er:YAG laser was used in 4 quadrants on the sclera to improve pliability & biomechanical efficiency of the ciliary muscles in 3 critical zones, for 20 patients. Patients were over 40 years of age and showed loss of accommodative ability. Visual outcomes were assessed using the Early Diabetic Retinopathy Study (EDTRS) logMAR charts, randot stereopsis, and intraocular pressure (IOP) was also assessed using a pneumatic tonometer before and after the procedure.

LSM provided improvement in both uncorrected and distance corrected intermediate (UIVA, DCIVA) and near visual acuity (UNVA, DCNVA) with no significant changes to their distance vision. Early results demonstrated that patients receive 5 lines of improvement in their binocular UNVA at 1 month postoperatively, compared to preoperative UNVA. Patients also showed improvement in stereopsis postoperatively.

Early clinical trial results suggest LSM to be a safe and effective procedure for restoring range of visual performance in presbyopes. Early results also suggest that LSM can improve intermediate and near visual acuity without touching the visual axis and without comprising distance vision or stereopsis. Data collection is ongoing.
