2019年2月26日 · Multifocal LASIK — sometimes called presbyLASIK — is an advanced type of laser vision correction surgery that changes the shape of the eye's cornea to create different power zones for seeing at varying distances.

Multifocal corneal ablation is one option for correction of presbyopia but application of this technique remains limited due to the temporary benefit of the procedure and the relatively high associated incidence of visual quality loss.

PresbyLASIK, in contrast to monovision LASIK, is a technique where cornea is ablated using multifocal ablation profiles to correct ametropia and presbyopia. With this approach, the same eye is utilized for both distance and near vision and is more physiological.

2023年10月18日 · Similar to monovision LASIK, presbyLASIK is a procedure that mimics monovision by creating multifocal corneal corrections. Unlike monovision LASIK, these adjustments are done on both eyes so...

Multifocal LASIK is an advanced form of LASIK vision surgery designed to correct presbyopia as well as nearsightedness, farsightedness and/or astigmatism.

2025年1月17日 · LASIK eye surgery is a popular option for people who want clear vision while reducing or eliminating the need for glasses or contact lenses. However, there are many things to consider before getting any type of laser eye surgery. This article covers what you should know about laser-assisted in-situ keratomileusis (LASIK).

Explanation of the Process: PresbyLASIK is a modified version of LASIK surgery that incorporates a technique called multifocal ablation. The intention of this procedure is to enhance vision issues that impact both close-up and distant sight by forming a multifocal layer on the eye’s cornea.

Whereas monovision LASIK improves distance vision in one eye and near vision in the other, multifocal LASIK (also called PresbyLASIK) creates multiple “power zones” across the surface of the cornea to improve the depth of clear vision focus at any distance.

2024年9月24日 · Multifocal lenses offer a gradual transition between near and far vision prescriptions. They allow you to read (close up) and look up from reading (intermediate) without changing lenses. Bifocal and trifocal glasses feature a sharp edge between the close-up and far-off part of the prescription.

2024年6月17日 · Multifocal LASIK. A more complex procedure that creates multiple zones of focus on the cornea itself. It’s not for everyone but it can provide a wider range of usable vision. LASIK surgeons might combine techniques, sometimes along with things like corneal inlays.
