LASIK Surgery

What is LASIK?

LASIK, which stands for Laser In-Situ Keratomileusis, is an extremely popular refractive surgery procedure used to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It’s so popular, in fact, that we’ve performed the surgery for over 10,000 patients. We can also use LASIK surgery to treat presbyopia in a procedure known as monovision correction.

Here are four things about LASIK that you might not know:

  1. LASIK is a method of using a laser to reshape the front surface of your eye, the cornea. By changing the shape of your cornea, LASIK allows your eye to focus naturally and improve the quality of your vision, eliminating the need for glasses.
  2. This reshaping process requires the laser to change the deeper central portion of the Cornea. In order to access this deeper tissue, older versions of refractive surgery physically removed the front tissue of the eye, allowing it to regrow over time.
  3. The next version of refractive surgery involved the surgeon using a hand-held instrument to partially cut a piece of the cornea and temporarily move it aside for the deeper section to be treated by the laser.
  4. The current and most advanced version of LASIK has eliminated the need for a hand-held cutting of the cornea.

Batra Vision has always been on the forefront of LASIK technology. We offer the latest generation of surgical lasers, which now have the advanced capability to make all corneal changes with laser precision. All-Laser LASIK gives our patients the most advanced vision correction procedure available today.

Recently, Batra Vision was the first provider in the United States to perform a commercial LASIK surgery using the Allegretto WaveLight 500 platform. WaveLight is the fastest refractive surgery platform available in the U.S. Its innovative engineering helps reduce the potential for stromal dehydration of the cornea, flap shrinkage, sensitivity to eye movements, and patient fixation fatigue.

Below, you will find information on LASIK surgery using Wavefront™ and IntraLase® technology, Epi- LASIK, and PRK. You will also find a set of general pre-op and post-op instructions we give each of our LASIK patients.

Frequently Asked Questions

Is LASIK right for me?
The best way to find out if LASIK is right for you is to schedule a consultation at our offices in San Leandro and Berkeley. During your visit, we will determine if you are a good candidate for LASIK and help you decide which refractive procedure or ophthalmic treatment is best for you. To schedule a consultation in the East Bay and Oakland area for LASIK surgery, contact Batra Vision Medical Group today.

How does LASIK Surgery work?
LASIK surgery is a quick and virtually painless refractive procedure performed on an outpatient basis. The procedure involves the creation of a thin flap on the cornea (the front of the eye) using either a precise instrument called a microkeratome or a surgical laser. This corneal flap is folded back allowing a refractive surgeon to reshape the cornea using a refractive laser. Once the cornea has been reshaped, the corneal flap is folded back into its original position where it will heal naturally without the need for sutures or stitches. LASIK surgery takes only a few minutes to perform per eye.

What results can I expect from LASIK Surgery?
The final results of LASIK surgery will vary from patient to patient given the unique nature of each patient’s eyes. Current statistics show that LASIK success rates can be as high as 98 percent, with patients achieving vision of 20/20 or better without the aid of glasses or contact lenses.

Wavefront™ Technology

Wavefront™ technology, a LASIK option available at our East Bay area offices, allows a refractive surgeon to generate an extremely accurate map of a patient’s eye. This specially generated map helps identify the unique aberrations (imperfections) that affect an individual patient’s vision. The information from this Wavefront™ map is electronically transferred to a computer that precisely controls the laser during surgery.

With Wavefront™, patients can expect high quality results following LASIK surgery. For instance, many patients report that contrast is better defined following Wavefront™-guided LASIK. Wavefront™ patients often experience better vision at night and in poor lighting than regular LASIK patients. Additionally, patients with thin corneas who were unable to undergo standard LASIK may still qualify for Wavefront™-guided LASIK. Recovery time from Wavefront™-guided LASIK surgery may also be more rapid than standard LASIK.


IntraLase® is another cutting-edge tool offered at Batra Vision Medical Group that offers patients added safety during LASIK surgery. In traditional LASIK surgery, a microkeratome is used to create a corneal flap. Though LASIK-related complications are rare, some complications have been attributed to the microkeratome.

Rather than using this device, Dr. V. Nicholas Batra can use the IntraLase® laser to cut the corneal flap. The computer-controlled laser is 100 times more accurate than a microkeratome. Additionally, IntraLase® allows some patients who were formerly not candidates for LASIK to undergo the procedure.

Monovision Correction for Presbyopia

Monovision refers to a refractive surgery practice in which one eye is corrected to view distant objects while the other is corrected to view nearby objects. Monovision correction is a common procedure for the treatment of presbyopia, an age-related condition in which the lens of the eye loses its flexibility and hence its ability to focus properly. If presbyopia is affecting your vision, we can help determine if monovision correction or another ophthalmology treatment such as lens implant surgery is best for correcting your vision.


Epi- LASIK, which stands for Epithelial Laser In-Situ Keratomileusis, is a refractive surgery procedure performed on patients who may not be ideal candidates for standard LASIK surgery due to thin corneas or other eye conditions. During Epi- LASIK, the epithelium, the thin outer layer of the cornea, is lifted without the use of a cutting instrument. The rest of the procedure is performed like standard LASIK in which the cornea is reshaped using a laser. While the recovery period following Epi- LASIK tends to be longer than with standard LASIK surgery, the results are still the same.


PRK, which stands for Photorefractive Keratectomy, is another alternative to LASIK surgery that is generally performed on patients with stable vision and low to moderate refractive errors. Unlike traditional LASIK in which a flap is created in the cornea, during PRK, the epithelium, the thin outer layer of the cornea, is removed. The cornea is then reshaped using a laser as in LASIK surgery. The recovery period following PRK is longer and generally less comfortable than standard LASIK since the epithelium must regenerate. Once the patient has recovered, the results of PRK are generally the same as LASIK.

Patient Instructions for LASIK, Epi- LASIK, and PRK

Below are general pre-op and post-op instructions for patients visiting our San Leandro, Concord, Oakland, and East Bay area offices for LASIK, Epi- LASIK, or PRK. You will receive a similar set of instructions that includes important reminder dates and detailed eye drop instructions prior to your refractive procedure.

Pre-Op Instructions

  • Use Zymar® twice a day for one week prior to surgery
  • Use artificial tears (Refresh Plus® or Bion® Tears) four times a day for one week prior to surgery
  • Wear warm, comfortable clothing the day of your procedure
  • If you currently wear soft contact lenses, please remove the contact lenses at least one week prior to refractive surgery
  • If you currently wear hard or gas permeable contact lenses, please remove the contact lenses after your exam
  • DO NOT wear any eye makeup or creams around the eye area for one week prior to surgery
  • DO NOT wear cologne or perfume on the day of surgery
  • You MUST have transportation to take you home. You will be unable to drive the rest of the day following surgery
  • If you are hungry, eat something light prior to your appointment
  • You will be given a mild tranquilizer, antibiotic eye drops, and anesthetic eye drops before the procedure
  • The actual procedure takes approximately 10 to 15 minutes. You should expect to be at the surgery center for approximately two to three hours

Following Your LASIK, Epi- LASIK, or PRK surgery

Following LASIK, Epi- LASIK, or PRK surgery, some patients may experience mild discomfort, tearing, and sensitivity to light for the first 12 to 14 hours. We recommend that you wear sunglasses outside for the first few days following refractive surgery. The majority of patients do not have pain after undergoing refractive surgery. The eye is generally not patched, but a clear shield is placed over the eye from the suction ring. This will clear in two to four weeks, and although not cosmetically pleasing, this is normal and will not result in any damage to the eye. No treatment is required for this.

A Few Do's and Don'ts After LASIK, Epi- LASIK, or PRK

  • DO keep your eyes closed as much as possible the first evening
  • DO take one sleeping pill upon arriving at home and one at bedtime. You will receive the sleeping pills the day of surgery
  • DO wear the eye shields at night while you are asleep for one week
  • DO be gentle around the eye when bathing for the first few days. Avoid soap and water directly in the eye
  • DO use eye drops as instructed. Drops will soothe and condition the front surface of the eye and promote not only comfort but healing
  • DO NOT read, watch TV, or work on the computer the day of surgery
  • DO NOT rub, scratch, or press on your eyes for two weeks after surgery
  • DO NOT swim in a lake, ocean, or swimming pool for two weeks or scuba dive for four weeks following surgery
  • DO NOT wear eye makeup for two weeks after surgery

Possible Symptoms During Your Recovery Process

You may experience glare, halos, sensitivity to light, and poor night vision for the first few weeks following LASIK, Epi- LASIK, or PRK surgery. This problem usually resolves after a few weeks to months.

If you experience increased redness, sensitivity to light, decreased vision, pain, or a white spot on the surface of the cornea, you must call us immediately. We are available 24 hours a day, seven days a week at our emergency number: (510) 895-3461.

If a touch-up or enhancement operation is needed, it is generally performed 12 weeks after the initial procedure. Enhancements are subject to a facility fee of $150 per eye. This covers sterilization of equipment and disposable items used during the procedure. After one year there will be a nominal surgeon’s fee.
