Cataracts are one of the most common eye disorders, a natural part of aging that affetcs everyone.  It's why cataract surgery is one of the most commonly performed and successful eye procedures in the world. It restores clarity, color, and brightness to vision through a painless outpatient procedure that usually takes less than 20 minutes to perform. At La Sight, we offer no-stitch, no patch, gentle-touch, and laser-assisted cataract care using the most modern technology available.  Results of care can have you seeing beautifully at distance and near, all without glasses!

What Is A Cataract?

As we age, the lens of our eye naturally starts to become cloudy.  This is called a cataract.  Like a foggy window, a cloudy lens is difficult to see through.  Most people over the age of 65 have already developed some clouding of their lenses; it just hasn’t begun to affect their vision yet.  But as cataracts progress, it becomes increasingly more difficult to see and do the everyday things you enjoy.

Cataracts can affect one or both eyes and are a normal part of the aging process.  Factors such as smoking, diabeties and high blood pressure will accelerate cataract development.  The good news is that cataract surgery and IOL implantation can quickly and painlessly replace the cloudy lens with a new, clear, artificial lens implant, restoring your vision.

Cataract Symptoms

Cataracts develop differently for everyone, and most people won’t even notice them at first.  Gradually, your lens will become cloudier, until it causes: 

  • Blurry or cloudy vision
  • Glare, halo, and increased difficulty with night driving
  • Decreased comfort with reading, even with proper-strength reading glasses
  • Difficulty seeing clearly even after updating your glasses prescription

Cataract Treatment

Early-stage cataracts do not need surgery, as there are several solutions that can be prescribed to provide you with adequate sight.  But eventually, the cataract will progress to the point you will need surgery. The only permanent correction for cataracts is to have the cloudy lens removed.  

Modern cataract surgery has become one of the safest and most beneficial operations performed today.  Typically, it is done on an outpatient basis under local anesthesia.  In the hands of a capable surgeon, the process should take 15 minutes or less to complete. Vision improvement can be seen immediately after surgery, and many patients are able to see 20/20 the day after their care.

Laser-Assisted Cataract Surgery

 More Accurate, More Precise.  A New Standard of Treatment.

Thanks to advancing laser technology, there now exists an option that can slightly greater precision and slightly greater accuracy than possible with even the hands of an expert technical surgeon: laser-assisted cataract surgery.

With traditional cataract surgery, several steps of the procedure are performed manually with hand-held instruments.  With laser-assisted cataract surgery, these steps can be performed with a computer-guided precision femtosecond laser.  Greater precision and greater accuracy can lead to better outcomes for patients.

Laser-assisted cataract surgery is a revolutionary advancement in eye care, and Los Angeles Cataract Surgeon Dr. David Wallace is proud to be one of the early adopters that recognizes the dramatic benefits the technology provides, and offers it to all his cataract patients. 

At our surgery center, we have both the OptiMedica Catalys laser and the Alcon LenSx laser available to use in performing laser-assisted cataract care.  We are one of only about 3 centers in the entire country to have access to both of these exceptional lasers.

Lens Implant Choices After Cataract Surgery

Eliminating Need for Glasses is Definitely an Option

The lens of our eye functions much like a camera lens.  It takes the light that enters our eye and focuses it on the back of our retina. The lens is also flexible, and tiny muscles in our eye bend the lens to focus on objects at all distances, both up close and far away.  As we age, our lenses become less flexible, causing the need for reading glasses.  Beyond that they become cloudy, causing the need for cataract surgery.   One very attractive option that is possible with cataract surgery is that it is now possible to reduce or eliminate your need for glasses altogether, thanks to new Lifestyle lenses and Refractive Services.  

Standard Monofocal Lens

The standard monofocal lens is the lens that is covered by Medicare and most private insurance plans.  It is a clear, single-focus IOL that can correct for near- or farsightedness, but not for astigmatism.  Since most people have some astigmatism in their optical prescription when they are ready to consider cataract care, and since astigmatism is not corrected by monofocal IOLs, it is likely that some eyeglass prescription will be necessary to obtain best distance vision after surgery with a standard monofocal IOL, unless the astigmatism is treated separately as done with our Refractive Services program.  Reading glasses will also be necessary if distance vision is optimized with monofocal IOL care.  The typical optical goal of surgery with monofocal IOLs can be either:

  • Full Distance Correction - intending to eliminate all near- or far-sightedness, but requiring some distance correction for astigmatism, and different correction for near; or
  • Monovision - wherein one eye is corrected for the distance range and the other is corrected for better clarity at a near range.

 Multifocal Lens

The multifocal IOL (intraocular lens) is a premium lens designed to allow you to see both up close and at a distance without glasses.  Two models of multifocal IOL are available in the US - the Tecnis Multifocal and the ReStor; we can explain the comparative features and benefits of each to you at the time of your consultation. These lenses function somewhat like bifocal glasses, with multiple concentric zones in the lens for viewing objects at far and rear range. Complete independence from glasses varies from person to person; you may still need glasses for certain tasks. Success is usually best when multifocal IOLs are placed in both eyes. 

With multifocal IOLs, both eyes must be optically 'tuned' to eliminate any distance prescription, including astigmatism.  That is why multifocal IOL placement is done in conjunction with refractive Services.  

Toric  Lens - Corrects Astigmatism 

This lens is specifically designed for people with more than small amounts of astigmatism.  Where monofocal IOLs can eliminate pre-existing nearsightedness (myopia) or farsightedness (hyperopia), toric IOLs can eliminate both nearsightedness and astigmatism (or farsightedness and astigmatism).  Since most people have some amount of near- or farsightedness and some astigmatism in their optical prescription by the time they are ready to consider cataract care,  use of a toric IOL can dramatically reduce the need to wear prescription glasses after cataract surgery.

Toric IOLs require extra planning before surgery, extra steps during surgery, and often additional measurements taken during surgery.  These steps are part of what contributes to the extra fees charged for refractive Services.

Crystalens - a "Pseudo-Accommodating" Lens

Separate from cataracts, as we age, the natural lens of our eye becomes less flexible, a condition called presbyopia.  This is what causes us to need reading glasses.  As the natural lens of our eye grows throughout life, it loses the ability to flex and thereby adjust focus from far to near. The Crystalens attempts to restore this flexible behavior, allowing us to naturally focus on objects up close and reduce the need for reading glasses after cataract surgery.

Crystalens care is usually performed targeting one eye for optimal distance correction and the other for intermediate range.
