Presby LASIK

Presby LASIK

PresbyLASIK is a surgical technique for presbyopic visual correction using Excimer LASER ablation.

PresbyLASIK treatment uses the principles of LASIK surgery to create a multifocal corneal surface aimed at reducing near vision spectacle dependence in presbyopic patients. Among the presbyLASIK techniques, the Excimer LASER ablation creates a central area which is hyperpositive for near vision leaving the midperipheral cornea for far vision.

The first presbyopia treatment with excimer laser was done with the monovision technique LASIK. Some authors consider the PresbyLASIK the next step after monovision LASIK.

While an overall improvement in visual acuity has been recorded for both near and distance vision, safety and quality of vision have been compromised. It has been reported that 20% of presbyLASIK-treated eyes lost two lines of best-corrected visual acuity at distance, and 52% of eyes lost two lines of best-corrected visual acuity for near vision, while only 48% of eyes achieved 20/20 uncorrected visual acuity.

More recently, Supracor, a central presbylasik technique designed by Technolas, has been CE marked and approved for hyperopic presbyopes. Dr. Soler┬┤s team, at Barcelona┬┤s OFTALNOVA-TEKNON clinic (www.cirugiadelavistacansada.es), have recently presented their one year results, at the 16th ESCRS winter meeting, and reported that more than 90% of patients had binocular distance and near vision of 0.8 or more, without glasses. Their results show symmetrical SUPRACOR (target -0.50 for both eyes) is safe, effective, and stable, in the short term. These patients will be followed-up as new protocols are being tested with asymmetrical Supracor ( emmetropia for dominant eye; -0.50 sphere for non dominant eye) aimed at younger presbyopic patients.
