Improvements in Eye Surgery


The eyes have been described as the windows to the world. Historically, when people experienced blurred vision due to cataracts or refractive problems, few treatment options were available. Today, advancements in technology and eye surgery have improved the vision of thousands of Americans.

Types of refractive procedures
Surgical treatment options help improve vision. During refractive surgery, doctors can change the shape of the cornea to allow the eyes to focus clearly. Currently, there are four types of refractive surgery techniques:

Astigmatic keratotomy (AK) – A surgical procedure used to correct astigmatism; AK may be used in combination with LASIK or PRK; surgeons typically make one or two incisions to help the cornea relax and become more round in shape

Photorefractive keratectomy (PRK) – Eye surgeons use a laser to reshape the cornea to correct mild to moderate cases of nearsightedness, farsightedness or astigmatism

Laser in-situ keratomileusis (LASIK) – Surgeons use a laser to reshape the underlying corneal tissue, allowing light into the eye and retina; used to correct nearsighted, farsighted or astigmatism

Radial keratectomy (RK) – Once the most frequently used surgery to correct nearsightedness, with advancements in LASIK and PRK; it has become less popular

Advancements for cataract treatment
As the eyes age, cataracts may form and make vision cloudy. About 50 percent of people between the ages of 64 and 74, and 70 percent of those ages 75 and older, develop some degree of cloudiness in their vision. If the condition worsens, they may be candidates for cataract surgery. During this procedure, the cloudy lens is removed and replaced with a clear artificial lens.

Recent technology innovations are helping to improve cataract surgery:

  • A new ORA device can be attached to the surgical microscope, enabling surgeons to be more precise while operating on the eye
  • ReLACS (refractive laser-assisted cataract surgery) is a new cataract procedure that uses a femtosecond laser, and other tests, to improve surgery outcomes

Sometimes after cataract surgery, a leak may develop around the incision. Until now, eye surgeons used stitches to close the opening. However, recently the U.S. Food and Drug Administration approved the use of a medicine gel to seal up these wounds. This substance is designed to gradually break down over a week’s time, and particles are gradually cleared away by the eye’s tears.

          There have been so many eye surgery improvements. I would feel so much more comfortable getting eye surgery now than at any other time in history. My brother-in-law just got eye surgery. I’ll have to ask him how it went. I might get it some day too.

            It is amazing to me how much surgery can help people who have been experiencing problems with their eye sight. It seems to me like our eye care technology has developed a lot over the years. It will be really interesting to see how workers will be able to continue developing technology in the future. Maybe some day if we are really lucky we will all be able to have almost 20/20 vision.

              That is interesting that cataracts can contribute to blurred vision. I am glad to know that there are treatments for cataracts such as surgery. That is cool that doctors are able to replace your blurred lens with clear artificial lens.

                It is really interesting to see all the improvements that we have made in the treatment of eye problems. I really like the improvements in cataract surgery that have been made: especially the microscope and a new way to seal the incision. It is cool that they have gel than can seal the incision without having to get stitches. Thanks for the info!
