Cataract Surgery

When the cataract begins to impair visual function or cause disturbing symptoms that interfere with a person's daily activities, it can be removed. Several additional testing procedures must be performed prior to cataract surgery, including measurements of the length of the eye and assessment of the curvature of the cornea.
Many options are available today for the prosthetic lens that replaces the crystalline lens with its cataract. Some lenses, called multifocal lenses or accommodating lenses, allow for correction of both near and distance vision.

Refractive Cataract Procedures

Refractive cataract surgery means performing cataract surgery with emphasis on achieving the best possible vision without glasses as possible, just as we do with our LASIK patients.

To achieve this we begin with the doctor making the key measurements and using the best and latest technology to achieve this. Of course, we need excellence in performing thousands of cataract surgeries. We offer a multitude of intraocular lens options. For patients with astigmatism, Dr. Ehrlich performs limbal relaxing incisions or LRI’s, or uses a special astigmatic or TORIC implant, or both.

For patients wishing to have the most freedom from glasses, he offers the Crystalens HD and ReStor multifocal lenses. Dr. Ehrlich was selected to perform the FDA trial that led to the approval of the Crystalens, an honor given to 18 surgeons in the United States who were felt to have the skills and track record to turn out the excellent results that would and did lead to the approval of the lens.

Refractive Lensectomy

A refractive lensectomy refers to performing refractive cataract surgery on a younger patient who does not yet have a clinically significant cataract but who desires the visual benefits from this technology. This includes patients who are too nearsighted or too farsighted to safely have LASIK, as well as patients who could have LASIK but desire both the far and reading vision available with a multifocal implant that is not available with LASIK. (The exception in LASIK is treating one eye for distance vision and one for reading, a process known as monovision.)




LASIK involves the use of an excimer laser to reshape the outer cornea of the eye. The laser treatment is performed beneath a superficial flap made in the outermost layer of the cornea using a special surgical instrument or a femtosecond laser. (Intralase)

Some patients have a cornea that is too thin or has mild abnormalities that are best treated by PRK. In PRK we do not make a LASIK flap, but use the same excimer laser to perform the same laser treatment on the outermost surface of the eye. The healing process is longer, but results are as good or better than LASIK.

Dr. Ehrlich was a LASIK patient in 2001, wrote a book reviewed in the Los Angeles Times in 2000, and ran a LASIK center in Sarasota, FL. In Colorado he performs his LASIK surgery at TLC Denver and Insight LASIK in Lafayette, Colorado.
