For many adults over the age of 40, the need for reading glasses becomes a daily inconvenience. This is often due to Presbyopia, the age-related loss of the eye’s ability to focus on nearby objects. Fortunately, modern ophthalmology offers innovative ways to address this without the constant hunt for “readers.”

What is Monovision?

Monovision is a technique where one eye is corrected for distance vision, while the other eye is corrected for near vision. While it may sound counterintuitive, the brain naturally adapts, seamlessly choosing the eye that provides the clearest image depending on what you are looking at.

• How it works: This can be achieved through contact lenses, LASIK, or during cataract surgery.
• The Benefit: It allows many people to perform most daily tasks—like checking a phone or driving—without needing glasses.

The Role of Prelex (Presbyopic Lens Exchange)

For those who are not yet ready for cataract surgery but wish to eliminate their dependence on bifocals or reading glasses, Prelex (also known as Refractive Lens Exchange) is a transformative option.

Unlike LASIK, which reshapes the cornea, Prelex involves replacing the eye’s natural lens with a specialized multifocal or accommodating intraocular lens before a cataract even forms. This procedure “pre-empts” cataracts, meaning once the procedure is done, the resident will never develop cataracts in the future. It is a proactive approach for those seeking a more permanent solution to vision correction.
