What is Laser Eye Treatment?

The treatment with laser is popularly known as the laser eye surgery and includes, among others, the measures for correction of the myopic, the hyperopic or the astygmatic eyes.

LASIK (Laser-Assisted In Situ Keratomileusis)

One of the most sophisticated forms of modern refractive surgery is (laser-assisted in situ keratomileustrie)

referred to as LASIK. This entails making an incision on the cornea, lifting deeper tissues up, and reshaping the surface using excimer laser with the intention of improving the eye’s ability to focus correctly. The laser in action results in fast healing and a commendable level of success, leaving people free of the need for the glass or lenses. However, depending on some factors will determine if this surgery is eligible of otherwise and this makes it imperative to consult a health care practitioner first before considering this procedure.

Benefits Of LASIK Surgery?

  1. Quick surgery with immediate results - You will regain your vision in the course of two weeks after the undergoing the 15-minute laser eye surgical LASIK procedure. Certainly, the waiting period is not necessary and even after a day of the surgery your vision gets better. However, full vision recovery lasts for fifteen days. However, during this period there’re minor limitations that you may experience such as no direct sunshine and do not swim.
  2. You save money in the long run - Some people shy away from undergoing LASIK surgery because they argue that their cost entails major investment. Though, the real fact is that you tend to save lots of money over time. You avoid spending so much time, money, and effort in frames, lenses contacts, contact solution, and optomettist sessions you will require for the rest of your life by only paying for a one-time laser eye surgery.
  3. LASIK surgery is pain-free - When people hear LASIK involves a laser, they assume that the surgery is painful. This is far from the truth. At most, you will feel a slight irritation in your eye during the surgery (Best eye specialist in Thane). In most cases, patients do not even require bandages or stitches and can get back to their normal life within 24 hours. 
  4. Low risk, high satisfaction - The study in 2015 on subjective quality of vision and satisfaction following LASIK found that 98.5 % patients were either satisfied or very satisfied and the other 98.5% felt that their initial goals of the operation were fulfilled. This included 79% of those people who reported being able to drive at night with an easier time than before. The occurrence of complications is a rare case and the complications if they do occur, end up being insignificant but can have an easy resolution.

PRK (Photorefractive Keratectomy)

A kind of laser surgery called Photorefractive Keratectomy is used for fixing vision through reshaping the cornea. It is not as straightforward or quick. Instead, the top layer of the cornea needs to be removed before using the laser to mold the underlaying tissues. PRK is used for the treatment of myopia, hyperopia, and astigmatism. This procedure is renowned for its precision towards providing perfect vision, however, recuperation might be slow compared to LASIK.

SMILE (Small Incision Lenticule Extraction)

SMILE which stands for Small Incision Lenticule Extraction, is a new technique. It is blade free and uses one laser. SMILE uses a femtosecond laser to create a lens-shaped disc of tissue within the cornea. This disc of tissue is called a ‘lenticule’ because it is lenticular in shape, this is removable. The lenticule size and shape is adjusted to the refractive error of the patient. 

  • The laser eye surgeon removes the lenticule through a 4-5mm incision on the cornea.
  • The removal reshapes and flattens the cornea and therefore corrects vision. 
  • The visual recovery is slower than LASIK.

LASEK (Laser Epithelial Keratomileusis)

LASEK which stands for Laser Assisted Sub-Epithelial Keratomileusis is a procedure similar to PRK. Like in PRK, the corneal epithelium is separated from the underlying stromal layer. But instead of completely removing and discarding this tissue, as in PRK, the ultra-thin "flap" of epithelium is pushed off to one side of the cornea (Eye care cornea centre in Thane), where it remains attached to the eye (like the thicker flap of corneal tissue created during LASIK surgery). 

EpiLASIK

Another PRK method version is called EPI-LASIK. The thin flap produced during LASEK surgery and the epi-lasik flap are extremely comparable. Only cells from the cornea's extremely thin epithelium—the outermost layer—are present in the flap in both surgeries. The process used to create the LASEK and epi-LASIK flaps differs. 
A sharp-bladed instrument is used to construct a LASEK flap. Using a device known as an epithelial separator, which has an oscillating plastic blade with a thin, blunt edge, the flap is separated from the stroma, the underlying corneal layer, during an epi-LASIK procedure. 
Additionally, unlike LASEK, epi-LASIK usually does not involve the application of an alcohol solution to the eye in order to release the epithelial cells from the underlying corneal stroma. 
The Epi-LASIK refractive surgery has been around since the early 2000s. People that would be most suitable for this type of surgery include those who have thin corneas, with insufficient tissue for LASIK. As with PRK the visual recovery is delayed and more discomfort is experienced during the recovery. In three days many patients do have 20:40 or even 20:20 but others take longer, possibly three or six months to reach their final result. Usually you can drive within a week after surgery. Epi-LASIK is not FDA approved.
