What Is Crystalens?

essentials_cataractsCrystalens helps patients suffering from cataracts and/or presbyopia achieve clear, crisp vision at all distances without the help of glasses. If your vision is clouded due to cataracts and/or reading has become difficult due to presbyopia, Crystalens IOLs can help you restore clear vision and eliminate your dependence on glasses. Few patients with Crystalens have experienced problems with glare, Cataractshalos and night vision. Crystalens is only lens that provides a single focal point throughout a continuous range of vision from far to near, unlike a multifocal lens that projects multiple images, requiring your brain to “adjust” to the differences. Crystalens is only lens that uses the natural focusing ability of the eye. Crystalens bends, flexes and mimics the movements of the eye’s natural lens.

Why Crystalens?

How Is Crystalens Different From Regular Cataract Surgery?

In the past, Cataract Surgery treated cataracts but the patient would still be dependent on glasses for most of their daily activities, especially for up close and intermediate. You are luck that there are options now for people undergoing cataract surgery. The Crystalens can correct far more than just your cataracts. The Crystalens is designed to offer you a full range of vision and reduce or eliminate your dependence on glasses.In addition Crystalens provides a single focal point throughout a continuous range of vision from far to near.  Crystalens has hinges on both sides of the IOL, so it can be moved more easily by the ciliary muscle, allowing the eye to focus more naturally at a greater range of distances.

Who Is A Candidate For Crystalens?

Typically Cataracts most commonly occur due to the aging process. Patients who have been affected by cataracts and other eye conditions typically are generally good candidates for Crystalens. Candidates can also include individuals of virtually any age who have cataracts caused by injury to the eye, overexposure to sunlight, genetics, and certain types of medications; however, intraocular lens implantation is generally performed on older patients. Dr. Davies here in San Diego will give you a thorough examination to determine whether you are a candidate for Crystalens.

What Are The Symptoms Of Cataracts?

As cataracts develop very slowly most people do not know they have them at first. However, the clouding progresses and vision will gradually get worse. Stronger lighting and eyeglasses can help improve vision. Nevertheless, eventually the vision impairment affects the patient’s ability to carry out everyday tasks. The following are the most common symptoms:


  • Blurry or hazy vision.
  • Dim vision that requires brighter lights in order to read small print.
  • Increased glare and sensitivity to light, especially in bright sunlight or while driving at night.
  • A yellowing of the vision.
  • Increased nearsightedness, requiring frequent changes in your glasses prescription.
  • Distortion, double images.

At What Point Do I Need Crystalens?


Happy-People1Ultimately the final decision for Crystalens is made by the patient and depends on how much the decreased vision from the cataract is bothersome. Davies Eye Center takes great pride in informing our patients on what options are best for them, based on their needs. Giving our patients the opportunity to choose for themselves is very important to us and our patients. In a lot of cases, the children of our patients eager to help there patient(s) begin to see better and enjoy their lives at a higher degree. Treating Cataracts  at an earlier stage makes for a quicker recovery and a technically easier surgery. Waiting until the vision is very poor can often make the surgery and the recovery more involved. In most cases, the patient and their loved one’s choose to have surgery before they develop vision-blocking Cataracts.


The California Department of Motor Vehicles requires that drivers have 20/40 vision (with or without glasses) in their better eye to qualify for a license. There have been patients choose to wait until their vision is approximately at this 20/40 level. However, many active patients who still work, drive, and use computers have higher demands for their vision. These patients tend to choose surgery at an earlier stage.

If you’re happy with your vision and it doesn’t cause difficulties with reading, computer use, driving, working, or your active lifestyle, then you should postpone the surgery. But the majority of our patients want and need better vision for their activities right now, and would like to enjoy their life at the fullest. If this is you, then schedule an appointment and begin to work towards restoring your vision.


What To Expect During Your Crystalens Procedure?

The Crystalens procedure is  performed at our Carlsbad facility on an outpatient basis. Dr. Davies will eliminate the cataracts by removing the eye’s natural lens. Then, the Crystalens implant will be inserted through a small, self-healing incision on the surface of the eye. The lens is typically folded to fit through the incision, but then unfolds and sets itself once it is inside the eye. The entire procedure usually lasts about 10 minutes.

What To Expect After Your Crystalens Procedure?

We advise our patients to rest for a while immediately after surgery, and we will give you a prescription for eye drops to care for your eyes in the days that follow. Most individuals are able to return to work and light activity within a day; however, patients are advised not to participate in activities which may cause blood pressure to rise or have the potential to incite pressure in or injury to the eyes. Full results of the Crystalens implantation may take several weeks to become apparent.
