Cataract  Center

What is a Cataract?

A cataract is a painless, cloudy area in the lens of the eye that blocks the passage of light to the retina. The retina is the nerve layer at the back of the eye. The nerve cells in the retina detect light entering the eye and send nerve signals to the brain about what the eye sees. Because cataracts block this light, they can cause vision problems.

Basic IOL

Best distance vision possible without glasses. You may need to wear glasses for distance, intermediate, and near vision. Most insurances will cover all or part of this lens.


Monovision is where your dominant eye is aimed for distance vision, and the non-dominant eye is aimed for near vision. This option is only available for patients utilizing monovision. Patients can do this in contacts or may have had prior refractive surgery. This option can be combined with Astigmatism Correction.

Multifocal Astigmatism

The Multifocal lens is designed to ideally free you from glasses after surgery. It is designed to provide a full range of vision and reduce or eliminate any dependence on glasses. 85-90% of patients are glasses free with this option. You may need glasses for certain activities or low/poor light conditions. The technology that allows for you to see the three levels of vision, distance, intermediate, and near, can cause a slight increase in glare and halos at night. This usually subsides within 3-6 months, as you adapt to the technology. This lens may not work well with patients that have other ocular problems, such as macular degeneration, epiretinal membrane (retinal wrinkle), or severe dry eyes.

Light Adjustable Lens

The Light Adjustable Lens is made of a special photo-sensitive material that changes the power of your implanted lens in response to UV light, increasing the likelihood that you will achieve your desired vision after cataract surgery. If you select the Light Adjustable Lens, the first step is to have your cataract safely removed and the adjustable IOL implanted. The cataract removal and IOL implantation procedure are the same as if you selected a non-adjustable IOL. What is unique about the Light Adjustable Lens is that, after your eye heals, you return to your eye doctor to have your vision tested during a routine eye exam. Based on this exam, you and your eye doctor will select a custom prescription for your adjustable lens based on your own eyes and unique lifestyle requirements.

Lens Options


First in Richardson to offer:


Light treatments are painless, non-invasive, and last approximately 90 seconds.


The Light Adjustable Lens is the only adjustable intraocular lens (IOL),

available that allows optimization of your vision after lens implantation and healing. If you and your doctor select the Light Adjustable Lens, the first step is to have your cataract safely removed and the adjustable IOL implanted. The cataract removal and IOL implantation procedure is the same as if you selected a non-adjustable IOL. After your eye has healed from surgery, you return to your eye doctor to have your vision tested.

Between 3 and 5 total light treatments,

                        each lasting approximately 90 seconds and separated by approximately 3 days, are required. The total number of light treatments is based on achievement of the desired vision outcome that you and your doctor selected. When you experience the results of your adjustments, you will better understand the value of adjusting and customizing your vision after your surgery.

Dr Kansal removed cataracts from both my eyes recently. He and his staff have been so wonderful. April walked me through procedures so there were no questions or surprises. The surgeries went beautifully and he also put in stints so I no longer have to use drops for glaucoma. Dr Kansal has seen me several times to explain what he is doing, answer all my questions and for follow up. He has worked with my insurance to coordinate payment. I would highly recommend him to anyone.

I recently had cataracts removed from both eyes. I have never had as excellent an experience as these procedures were. I highly recommend Dr.Kansal to friends & family so you can tell what great respect I have for him. Even he was startled at the improvement in my far vision after the procedures were done. If you need to have this procedure done, but have been too scared, I highly recommend that you wait no longer.


David R.

Dr. Kansal and his staff provide excellent professional services. My recent cataract surgeries with lens implants have resulted in 20/15 vision in both eyes. Dr. Kansal takes the time to get the best readings he can in preparation for the surgeries. His goal is perfection. He meets that goal.
