PresbyLASIK

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 eyes lost two lines of best-corrected visual acuity at distance and 52% of eyes lost two lines of best-corrected visual acuity at near, while only 48% of eyes achieved 20/20 uncorrected visual acuity.

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 (more highly curved) for near vision leaving the midperipheral cornea for far vision.[1] Alternatively, the Excimer LASER ablation can create a central area, which is relatively flatter for more distance vision and a midperiphreal ring of the cornea that is more highly curved dedicated to near vision. [2] The first presbyopia treatment with excimer laser was done with the monovision technique LASIK. PresbyLASIK was first performed in the United States by Epstein who has also extended the treatment to surface laser vision correction (presbyPRK). [edit]
