Nidek Laser (EXCIMER Laser)

The use of the EXCIMER LASER in corneal refractive surgery has greatly increased the safety of the procedure as the refractive correction is achieved by removing as little as 10-20% of the total corneal thickness.
The EXCIMER LASER is a “cool” laser, and does not generate heat in the cornea. The laser energy destroys intermolecular bonds in the corneal tissue resulting in tissue removal by a process termed “photoablative decomposition”. The exquisite precision with which the tissue can be removed, and the absence of thermal damage, render this laser suitable for surgery on the delicate cornea.
Removal of corneal tissue alters the corneal contour. By specifically removing tissues from different portions of the cornea, the surgeon is able to correct the different refractive errors. Removal of the central corneal tissue in a circular fashion results in central flattening and corrects myopia.

How does Excimer Laser Work?

A recent advance in the treatment of such high refractive errors is a procedure termed Laser-Assisted In Situ Keratomileusis (LASIK). In this surgery, a flap of superficial corneal tissue is cut using a motorized blade. The flap is lifted exposing the underlying corneal stroma. The excimer laser is then used to perform the appropriate tissue removal in the corneal bed. At the conclusion of laser delivery, the corneal flap is repositioned in its original position. The flap adheres to the underlying corneal stroma without the need of sutures

The laser removes tissue from the center of the cornea (in the case of myopia) to flatten its curvature and correct nearsightedness. In the case of farsightedness, the tissue is removed from the periphery of the cornea to steepen its curvature. The laser essentially reshapes the cornea's front surface. To do this, the corneal stroma (tissue beneath the corneal epithelium) must be exposed. This can be accomplished by directly removing the corneal epithelium with a laser (PRK) or by creating a corneal flap with a microkeratome (LASIK).

The goal is to reshape the cornea so that rays of light that enter the eye are focused clearly onto the retina. The excimer laser produces a cool, ultraviolet beam of light (193 nanometers in length) that literally vaporizes the tissue as it breaks carbon-to-carbon bonds. The tissue is removed in a precise fashion on a microscopic level, leaving the adjacent tissues unharmed. This vaporizing process is called photoablation.

Advantages of Blade Free Lasik

The various advantages of LASIK LASER are as follows:

  • Faster LASIK procedure time, increasing patient comfort
  • Stronger, more secure LASIK flaps
  • Improved corneal sensitivity
  • Fewer dry eye symptoms
  • More predictable corneal flap thickness
  • Decreased risk of corneal abrasions during surgery
  • Decreased risk of induced astigmatism after LASIK

Myths / Frequently Asked Questions about LASIK

1Are Laser (LASIK) Procedures Safe?
Answer: LASIK procedures are very safe. These procedures are also US -FDA approved certification, which means they have been given safety clearance for Human Eyes. However, like any other surgical procedure it can have some complications which are extremely rare if a proper screening check is done prior to the procedure. Some patients might experience mild dryness in eyes which usually relieved by lubricating drops and disappears over time. Some may also experience temporary halos during night time which also reduces with time. Immediately after LASIK one might experience mild heaviness and blurring of vision. These are due to the effects of numbing eye drops used during the procedure. All these are rare and can be easily managed by your doctor. Nobody, in our surgical experience, has ever lost sight due to this procedure.
2What if I am found unfit for LASIK?
Answer: 98% people are usually found fit for LASIK. If, however you are not suitable for LASIK, your doctor may suggest you alternative procedures for vision correction such as ICL, Advanced Surface Ablation etc.
3I want a flapless procedure. What are my options?
Answer: No Laser Vision Correction procedure i.e. LASIK, is completely flapless. The only procedure which is 100% flapless is ICL, where a lens is inserted in the eye.
4 What precautions should be taken after LASIK?
  • Do not touch your eyes with fingers. Mop tears with soft tissue paper. Do not use handkerchief
  • Keep your eyes closed as much as possible after laser treatment on the laser day.
  • Eye drops to be started on the laser day. Pull lower lid and place one or two drops on the eye in the gap between the lid and the eyeball
  • Wear dark glasses continuously throughout the day for the first 3 days. On the first three nights, use protective eye shields provided to you by the LASIK centre. From 4th day onwards, use dark glasses only when outdoors up to 15th day. The purpose of dark glasses is to prevent your hands from rubbing the eyes. It also serves as a small protection against dust. Exposure to sunlight or room light is not harmful to the eyes.
  • Stay in clean environment- Avoid kitchen and smoke for 1 week.
  • Mobile phones may be used from the next day
  • Computer use, watching TV, reading etc. can be started from the 2nd day in moderation. There may be strain on eyes initially which is normal.
  • Take a bath neck down for 1 week. During this period, clean your eyelids lightly with boiled cotton once in the morning to remove deposits from the lid margin, taking care not to touch the black portion (cornea) of the eye. Wipe face lightly with a clean towel without rubbing your eyes.
  • From 2nd week onwards, take a normal bath from head downwards with your eyes closed as a precaution. A little water entering your eyes now is a very low risk.
  • After 2 weeks, you can return to normal bathing
  • Light activities can be done the very next day. Do not do heavy exercises for 7 days. Sports activities can be done after 1 month.
  • You can have your normal food after laser treatment.
  • Avoid car driving for 2 days, and driving a bike for 2 weeks.
  • Do not splash water into eyes for 2 weeks. Splashing water into the eyes as a habit is best avoided as it washes away all the natural oils of the eye, inducing dry eyes. Splashing to wash away some dust particle is acceptable
  • Smoking and drinking to be avoided for two weeks.
  • Do not use any eye make up for 2weeks. Threading of eyebrows may be done after 2 weeks taking care to avoid too much pressure on the eye.
  • Facial massage should be avoided on the eye area for 3 months.
  • Avoid vigorously rubbing your eyes for 3 months.
  • Avoid swimming, water diving for 3 months.
  • Cosmetic contact lenses can be used after 3 months.
5Does the Procedure Hurt?
Answer:The laser procedure itself does not hurt. A slight pressure may be felt during the procedure. There is a possibility of some degree of discomfort after the procedure for 3 to 4 hours, which is easily controlled by medication. If discomfort persists, you should contact your eye doctor.
6I’m planning to get LASIK done, how many days’ leave should I apply to the office?
Answer: Most of the routine work can be done after 7 days. Jobs that are more physically demanding and involve exposure to liquids or dust might require a more graduated return to full activities, but are best discussed with your surgeon.
7 Will I be totally free from spectacles?
Answer:97% of the people will be totally free from their spectacles. 3% will have mild variation from their zero targeted correction due to varying healing patterns in different individuals, but will have their dependency reduced on spectacles. After 3 to 6 months, a laser enhancement can be attempted to correct these individuals further. People over the age of 45, who opt for distance vision correction, may need reading glasses.
8 For how long will I have to put medications?
Answer:Usually a patient is on medicated eye drops for 4 weeks and has to use lubricating eye drops for at-least three months
9Can I use spectacles or contact lenses after the surgery?
Answer:If the need arises, yes they can be used after speaking with your doctor.
10Can I use eye makeup / cosmetics after the surgery?
Answer:Eye makeup can usually be used after two week of treatment after consulting your doctor.
11Will this treatment have any effect when I undergo a Cataract Surgery later in life?
Answer:When you plan to undergo a cataract surgery later in life, one should inform the doctor about any previous procedures so that the treatment plan can be modified accordingly.
12Are the results achieved from LASIK permanent?
Answer:The effects of LASIK on the cornea are permanent. Sometimes, internal changes within an eye may come with age and these may have some effect on the overall visual status. For example, myopia may progress even in later years, or a person may require reading glasses with normal ageing process usually seen after 40 years of age.
13 What is the worst possible complication?
Answer:Infection is a serious complication and could lead to deterioration of the cornea. Infection is usually rare and can be well controlled with medications with little or no loss of quality of vision. At our Centre, we have had no case of infection till date.
14How would the eye behave after 30 years from now?
Answer:The medical community can only speak of the future by accessing the data from the surgeries performed within the last 20 years. The data reveals a very positive healing response of the eye giving doctors no reason to be concerned about effects beyond 30 years.
15Have any doctors had LASIK correction themselves?
Answer:Yes, many in India as well in several other countries. We have also operated on several doctors including eye specialists.
16Can I drive home after LASIK?
Answer: No.
17How many checkups will I need after LASIK?
Answer:Follow ups after LASIK are usually done the next day, next week and then monthly for 2 months. However these are best suggested by your doctor.
18Is LASIK the suitable option for Amblyopia?
Answer:No. Please understand that LASIK is known to correct refractive errors. In case of lazy eye, no refractive surgery restores vision.
