The Light Adjustable Intraocular Lens

The RxSight™ Light Adjustable Lens (LAL) is rocking the world of ophthalmology because it is the first and only cataract lens replacement in which the prescription power can be modified following cataract or Refractive Lens Exchange (RLE) surgery by a Light Delivery Device. This specialized lens allows you and your surgeon to customize your vision after your eye has healed from the natural lens removal.

"I recommend that anyone and everyone considering eye surgery call San Antonio Eye Specialists. You’ll be happy you did."

"I have to share that this experience has been fantastic. I came initially to inquire about lasik and found that light adjustable lens replacement was best for me. Having worn glasses for years and struggling with contacts to fit right etc, I was excited but nervous to press forward with eye surgery, however,  the doctors and staff and San Antonio Eye Specialists were simply phenomenal in making me feel comfortable and confident in my decision. They made sure I was informed of all the information and answered all of my questions (I had A LOT of them). The surgery in itself was painless. OMG I love my 20/20 vision!!! "

How Is The Light Adjustable Lens Power Changed?

The Light Adjustable Lens (LAL) is made of a special photosensitive material that changes the shape and power of your implanted lens in response to ultraviolet (UV) light source. You and your physician will have the unique ability to adjust and preview your vision until it meets your personal desires and lifestyle requirements. The vision may be modified for each eye.

The cataract removal and IOL (Intraocular Lens) implantation procedure of the LAL is exactly the same as a non-adjustable IOL. The difference with the LAL lens is that in the weeks that follow cataract removal, your surgeon will customize your vision through a series of non-invasive UV light treatments that take only a few minutes per eye. You may need 2 to 4 total light treatments over a period of 1 to 2 weeks (sometimes more) to reach your vision goals. Once your vision is adjusted, a final light treatment is used to lock in the desired results.

The Light Adjustable Lens (LAL) delivers superior vision outcomes that non-adjustable IOLs cannot match. In a clinical study, the majority of patients who received the Light Adjustable Lens achieved 20/20 or better vision at 6 months without glasses. 1

What Are The Benefits Of The Light Adjustable Lens?

No human has both eyes identical in curvature, size or prescription. Each LAL is tailored to that specific eye and treats astigmatism, nearsightedness, and farsightedness. If there is any residual refractive error following cataract surgery, simply fixating on the light source for a calculated amount of time lasting a couple of minutes or less will lock in the tweaked prescription thereby resulting in 20/20 or better vision.

Who Is Eligible For The Light Adjustable Lens?

Patients with pre-existing astigmatism of 0.75 diopters or more who need cataract removal are considered candidates. Cataracts can develop at different ages from various causes unrelated to the natural aging process.  Some factors attributing to cataracts are genetic anomalies, eye injuries, excessive sunlight exposure especially in tropical areas, diabetes, use of certain medications, obesity, and uveitis. Even patients wanting Refractive Lens Exchange or Monovision are candidates. Pretty much anyone wanting to remove their natural lens and replace it with the Light Adjustable Lens with overall good eye health and general health are considered candidates. The beauty and ease of the LAL is its diversity with ease in changing the lens prescription to be tailored to the patient's visual preference. The LAL is especially beneficial for patients who have previously had LASIK, PRK, RK, and other refractive procedures at some stage of their life and must now undergo a lens replacement.

Why Choose San Antonio Eye Specialists?

Our founder, Nader G. Iskander, MD, FACS, is one of a few fellowship-trained refractive surgeons in San Antonio. He has performed thousands of laser-assisted cataract removal surgeries using advanced laser technology and he is certified on both the LENSAR AND LenSx™ Femtosecond laser technologies. LENSAR™ laser system uses augmented reality to collect biometric data and render a 3-D model of the patient’s eye, which is used to create a customized treatment plan. During surgery, the system’s laser is used to create corneal incisions with more accuracy in comparison to a manual incision and one that is so small it does not require sutures. The cataract removal is safe, precise, and results in better visual outcomes for our patients. Additionally, San Antonio Eye Specialists offers a wide variety of lens implant options, so patients get the lens replacement that is best for their lifestyle.

- Chris M.

"I couldn’t be happier with my eye surgery! I had cataract surgery with a multi focal lens on my left eye last week, and Dr. Iskander performed the same procedure on my right eye yesterday. Insurance didn’t cover most of my procedure, but my results were worth every penny. I had terrible vision and wore hard or gas permeable contact lenses for almost 50 years; now I can see 20/20 without any glasses or contacts! Amazing! Dr. Iskander and his staff are awesome!"

- Shelley M.

"Dr. Iskander and the San Antonio Eye Specialists team are highly skilled, knowledgeable, caring, and supportive through what may be considered a procedure to be held off for fears of the outcome. There is nothing to worry about. Dr. Iskander addressed all my questions and concerns with care and patience. His skill for eye surgery is excellent. I had both eyes operated on for cataract removal and lens implants. I no longer need glasses. I thank Dr. Iskander and his team for all they did for me."

Frequently Asked Questions About The Light Adjustable Lens (LAL)

Who is a candidate for the Light Adjustable Lens (LAL)?

arrow icon

Anyone who needs to remove their natural eye lens and replace it with an Intraocular Lens (IOL), such as the LAL.  So, a patient with a cataract can have the LAL.  A patient who does not have cataracts but wants to benefit from a lens exchange can have the LAL.  

The LAL is especially beneficial to patients that had previous refractive procedures earlier in life, such as LASIK, PRK or Radial Keratotomy (RK) because the calculation of the Intraocular Lens (IOL) becomes tricky on a previously operated eye.  Fine tuning the lens prescription after the LAL placement helps surgeons achieve the desired vision patients seek.

What are the benefits of the Light Adjustable Lens (LAL)?

arrow icon

The unique beauty of the LAL is that it allows patients to preview their vision after surgery and assess if it meets their personal needs and lifestyle requirements. Patients can go home and try the lens and see if it is precisely as they want or return back to the office for nonsurgical modifications.  If the vision needs to be tweaked or adjusted, it can be done simply by looking into a UV light source called a Light Delivery Device (LDD) for a couple of minutes or less to lock in the prescription by changing the lens shape and power in the implanted lens. This can be done repeatedly at different appointments until the patient is satisfied with the vision. The Light Adjustable Lens is the only one of its kind from RxSight.

Can my lens prescription change if I look at the sun following surgery?

arrow icon

Looking directly at the sun is not advised ever, but we provide 2 sets of glasses following surgery: clear and dark glasses. The clear glasses are for indoor use and the dark glasses for outdoor use. There is a 4-6 week window of locking in the lens prescription and for that duration, those specific glasses are advised to be worn. After this time, the prescription is fully locked in.

Is LAL covered by medical insurance?

At your appointment, we will discuss all costs associated with surgery and if any portion is covered by your specific insurance carrier and what is considered elective and out of pocket.
