LASIK vs. Cataract Surgery

OPHTHALMOLOGY

As vision declines, many people begin considering LASIK surgery. However, sometimes what the patient actually needs is refractive cataract surgery. Only a board-certified ophthalmologist knows for sure.

“I had forty-plus years of it, beginning back when lenses were made of actual glass and were easily broken by active children,” reflects the supply chain manager, “so I experienced all the heartbreak that went with glasses.

“Next, I went through the old, hard, plastic contact lenses, followed by soft lenses that, because of my astigmatism, were weighted such that, if I lay down to watch television, they went out of focus. I had to sit at attention.

“Then, as I aged, my eyes became drier and I began having trouble tolerating contact lenses of any kind.”

Rudy admits that, by that point, he had had enough: “I decided to find out if I was a candidate for LASIK.”

His optometrist referred him to Robert J. Weinstock, MD, known as “Dr. Rob” by his patients. Dr. Weinstock is board certified by the American Board of Ophthalmology and fellowship trained in cataract and refractive surgery. He was the first eye surgeon to successfully remove a cataract through a 1.2 millimeter incision (1/16th of an inch) and has been invited to lecture and teach other surgeons from around the world on this safer, less invasive technique for removing cataracts.

“LASIK is a procedure used to reshape the inner corneal tissue of the eye,” explains Dr. Weinstock. “Patients who can benefit from LASIK have a cornea (the front surface of the eye) that is shaped either too steeply or too flat. When the cornea is not shaped to match the length of the eye, light rays do not focus properly and it causes either nearsightedness or farsightedness.

“During LASIK surgery, I use a laser to remove tiny bits of tissue from the cornea. For those like Rudy who are nearsighted, I flatten the cornea; for farsighted patients, a steeper cornea is created.”

Rudy remembers his first appointment with Dr. Weinstock.

“The first thing I noticed was that the doctor was a lot younger than I was,” notes Rudy, who was 55 years old at the time, with a laugh. “But I didn’t think that was a downside. In the field of eye surgery, where technology is often moving at the speed of light, I saw his age as a positive because he wasn’t encumbered by the old rules and techniques. He knew what could be done and was looking into the future; that was really important to me. Even as such a young man, he had a great record and he was moving forward all the time.”

After a thorough consultation and careful examination to determine the type of correction Rudy required, Dr. Weinstock performed LASIK surgery on both of Rudy’s eyes.

“It went wonderfully,” observes Rudy. “I could see perfectly even coming out of the operating room. There was minimal discomfort and it gave me 20/20 vision.”

Refractive cataract surgery

“Many patients come in to see me because their vision is getting worse for distance or near and they think they need LASIK,” observes Dr. Weinstock. Often, however, the real issue is an early cataract that is causing their vision loss.

“In our youth, our natural lenses are soft and flexible, but for most people as they enter their early forties, their lenses become less pliable. People often turn to reading glasses in order to see close-up. This is typically the earliest sign of a cataract.”

A cataract is an opacity, or clouding, of the natural lens in the eye, which lies behind the iris and the pupil. In a healthy eye, light passes unobstructed through the clear lens, allowing images to be sharply focused on the retina. However, as people age and the lens becomes clouded, light is blocked and a blurred image forms on the retina, which passes this poor image along the optic nerve. As a cataract develops, it offers less clear lens area for the passage of light.

“A cataract grows like an onion does, adding layer upon layer,” educates Dr. Weinstock. “Eventually, the cataract becomes very hard and dense, which is when the vision becomes cloudy, resulting in an indistinct image and making it more difficult to see. It is what we refer to as lens dysfunction.”

Rudy observes that, even with the excellent vision that comes with LASIK, his eyes continued to age: “After several years, I began noticing that my vision was deterioratingparticularly my night vision, and more in my left than my right eye.

“Because it’s hard to mess with success, I consulted Dr. Rob about it.”

“Traditionally, for patients like Rudy with both astigmatism and cataracts, few ophthalmologists have corrected astigmatism at the time of cataract surgery, but that is beginning to change,” observes Dr. Weinstock.

“When a patient has an astigmatism as well as a cataract, replacing the cataract with either a standard lens implant or a Crystalens® Lifestyle intraocular lens (IOL) will not correct the astigmatism. The patient will still require glasses.

“However, during cataract surgery there is an additional procedure we can perform that corrects the astigmatism. The surgery, known as a limbal relaxing incision, or LRI, is comparable to letting out the seams in a dress. Using precisely measured limbal relaxing incisions, we relax the steep angle in the cornea, which reduces or eliminates the astigmatism. For many of these patients, more advanced implants can then be used to reduce the need for reading glasses.”

Another option for patients who qualify is a lens replacement implant known as a toric IOL, adds Dr. Weinstock: “It can correct both vision and astigmatism simultaneously without having to make extra incisions on the eye.

“Because everyone’s eyes are different, the best results for some patients may be a combination of the two: a toric lens with additional LRIs.”

Two and a half years ago, Rudy chose to have the premium IOL Crystalens with the LRI for his left eye. In May 2010, Dr. Weinstock performed the same treatment on Rudy’s right eye.

“The challenge with any form of astigmatic correction is to be accurate and predictable in order to provide the desired results for our patients,” emphasizes Dr. Weinstock. “The new ORange™ Intraoperative Wavefront Aberrometer by WaveTec Vision Systems can help, and presently there are only four facilities in Florida offering this technology.”

The device is designed to provide a real-time analysis of the changes during surgery. With this new technology, the eye can be measured before and after the LRI so Dr. Weinstock can determine more precisely whether the astigmatism has been corrected or whether the incisions need to be a little bit deeper or longer, or if an additional incision is required right then and there to ensure the patient gets the best possible result.  Dr. Weinstock was the first refractive specialist in Pinellas County to use this technology, and Dr. Rob Weinstock, Dr. Stephen Weinstock, and Dr. Neel Desai all use WaveTec at The Eye Institute of West Florida.

Excellent results

“Once again, my results were absolutely wonderful,” assures Rudy. “Dr. Rob performed the surgery over lunch. I went home at two. By the next day, when my pupil had reverted back to its normal state, my vision was perfect.

“I’m sixty-five years old and I can read the newspaper classified ads without glasses*, yet I can see a road sign two blocks down the street, also without glasses. I spend long hours at work, a lot of computer time, and I’m just happy.

“I like the organization at The Eye Institute of West Florida; it is very efficient and the people are all very nice.

“I’m confident in Dr. Rob, and he is confident in himself, which I like very much.” FHCN – Kris Kline
