Why Go for Aspheric Eye Surgery?

Wednesday, May 25th, 2011

Swimming, flying an airplane and vigorous activities such as rugby are some of the things an individual with eye problems must pass on. Although it may sound sad and harsh but the issue of safety of the individual himself and those around him are just too important to ignore in lieu of passion or desire.

Fortunately, in the year around 1950, a talented ophthalmologist by the name of Jose Barraquer developed the first microkeratome. It is a procedure wherein refractive errors of the eyes are corrected by altering the shape of the cornea. This method is called Keratomileusis.

This scientific development paved the way for further advancements. Among it was the first laser guided eye surgery which is no other than LASIK also known as laser assisted in situ Keratomileusis. LASIK gave amazing results to the clients who have undergone each. However just as no two eyes are the same, scientists saw the need for more specified procedures.

This gave way to the development of LASEK. LASEK uses a much finer blade and unlike LASIK leaves the stroma uncut. Further advancements finally led to the latest laser guided eye surgery of today which is LASAK.

However there are procedures that can further specify and guide the procedure. This is no other than wavefront and aspheric. Because the cornea of the eye is not round as most people think it is, doing a procedure that assumes it is may incur unwanted side effects. With the aspheric eye surgery however what happens is that the surgeon evaluates the shape of the cornea before the start of the surgery. Then he decides which laser assisted eye surgery is best to perform on the said individual. With aspheric eye surgery, the post operative cornea resembles the shape of pre operative cornea thereby avoiding spherical aberrations.

Why Lasik Surgery Is Very Safe

Thursday, January 7th, 2010

A Lasik eye surgery can seem to be a big thing for many people; and many of them do not want to ask all the questions. People fear the unknown; and the Lasik procedure is not one of the most talked about issues. In this article you can read about some of the most commonly fears and how most people experience the operation.

A most common fear when thinking about a Lasik procedure, or really thinking about any surgery in general, is the possibility of pain during or after the operation. Since the Lasik surgeon works on patients that are conscious, this is a widely held apprehension. In every operation the Lasik surgeon applies numbing drops into the eyes before the procedure starts, and the patient is also given a mild sedative to relax them and make sure that they are comfortable. Though a small pressure to the eye may be felt during the Lasik procedure, the process itself is relatively pain free.

The surgeon does use a laser in the eye to help reshape the cornea during the Lasik procedure. Many folks are worried about the laser being shone directly into the eye, or that they might look away and, due to this, develop a serious complication with their eyes and the Lasik laser beam effects. In actuality, the laser is only active for ten to fifteen seconds for each eye, and the Lasik machine has a tracking system that allows the beam to be on only when the eye is in the correct position.

Another common fear is the fear of “the scalpel”. All the eye surgeries use either a very small microkeratome blade or the laser itself to create the flap that is needed to perform the laser operation. So there is no reason the fear about a scalpel, because it is actually not used.

There are many horror stories when it comes to operations. So it is natural to wonder if there is any risk; like going blind. But according to the government statistics created by the FDA, there has never been reported any case of blindness due to a Lasik surgery.

The reality is that the risk of major permanent complication less than one percent. And if we include the minor complications too (like light halos) the risk is less than 3 percent totally. It is only a very few rare cases where a Lasik surgery will not improve the vision.

If the thought of being awake and having your eyes open during the Lasik procedure bothers you, remember that you will be given a mild sedative for the procedure, and that your eyes will have numbing drops administered to them.

Is it more the thought about the Lasik physician’s hand close to the eye that bothers you? Then just think about that your eyes will be applied with drops that make your vision black out for the ten to fifteen seconds the operation takes.

Everything About LASIK Surgery

Wednesday, November 4th, 2009

Because it is gentle, fast, efficient and with few complications, the LASIK surgery is the most popular eye surgery type today. It is a great laser surgery for most people; no matter if they suffer from farsightedness, nearsightedness and/or astigmatism.

LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be put back again.

It only takes a few minutes to perform the the surgery. The eye will be dripped with anesthetics and most people will not feel any pain at all. When the eye is anaesthetized the cut in the cornea can be made and the laser surgery can be done.

The actual laser treatment takes between 30 seconds and two minutes. A special laser called an Excimer laser will be used. It is specifically designed to operate in the eye’s sensitive tissues. Finally the corneal flap is put back again.

It is possible to leave the operating room right after the surgery. The eyes may sting a little bit, so it is advised to rest for the rest of the day. A nap can also help.

Most people will already at that time feel that their sight has improved. Over the next weeks will stabilize.

After the eye surgery the eyes can feel a little dry. It is therefore recommended to drip them with a little salt water.

All studies indicate that a permanent sight improvement is provided by the LASIK operation. And previous bad eyesight will not return again. But a possible, natural change of sight in the future is not possible to prevent by the operation. So the surgery should not be done before the sight is stable.

The LASIK surgery can also not prevent the natural age-related long-sightedness that even normally sighted people will experience.
