All About Light Adjustable Lenses

Refractive Lens Exchange (RLE)  is also known as Clear Lens Extraction (CLE) because the patient has a clear eye lens without the presence of a cataract.  RLE or CLE is a very safe, effective and life-changing procedure common among presbyopic patients.  Presbyopia is a refractive error caused by the natural aging process seen with patients in their 40's and 50's whereby the natural eye lens can no longer focus on objects up-close, so patients need to hold objects further out at arm's length to see clearly.  But there comes a point, where even the farthest stretched hands cannot be far enough and patients struggle to focus clearly.

The benefit of having an RLE is that the patient will be able to see clearly without the aid of glasses or contact lenses and later avoid having cataracts since the natural eye lens would have been replaced with a synthetic intraocular lens to correct the refractive error.  Various lenses are available depending on the patient's visual needs such as monofocal lenses, multifocal lenses and Toric lenses to correct for astigmatism.

What Are Light Adjustable Lenses?

The latest and only intraocular lens that can have the lens prescription changed after surgery is created by RxSight called the Light Adjustable Lens (LAL).  This unique lens uses photochemistry and diffusion when a special UV light source called a Light Delivery Device is directed onto the silicon lens to lock in and fine-tune the end prescription of the lens allowing more predictability in the outcome.  The LAL treats nearsightedness, farsightedness and astigmatism.  If there is any residual refractive error following surgery, simple fixation on the light source for a certain duration of time will help tweak the prescription to 20/20 while allowing the patient to test the vision in the real world and return again to the office for additional treatment until the desired vision is achieved.
