  1. LASIK By Dr. Agarwal’s Eye Hospital

  2. Can LASIK be done again? •  The patient satisfaction rate of Lasik procedure is more than 95%. The wonderful thing is that most people never need a repeat procedure. • However 2-5% patients may need a repeat procedure. It can be either due to less than desirable outcome the first time (some residual number after Lasik correction) or some numbers coming back (regression) in future.

  3. Repeat LASIK also called enhancement can be done even years after the first one. Despite a high LASIK retreatment success rate, it is important to weigh the risks against the benefits and appropriately answer the crucial question of why, when and how to re-treat.

  4. 3 Important Considerations ; • Timing– Repeat Lasik procedure is done only after the stabilization of the residual power after laser vision correction. It is better to wait for at least 2-3 months and achieve stable power before considering lasik enhancement. Some amount of fluctuation is common for a few months after the first procedure. Hence it should not be called a lasik failure till then.

  5. Repeat pre- LASIK evaluation-To determine whether someone is a good candidate for a repeat LASIK, we have to re-evaluate and perform a detailed pre LASIK evaluation all over again. Among other things, we need to check whether enough corneal thickness is present below the flap for a second surgery. The aim here is to again ensure that the repeat procedure is safe and will not result in any undesirable long term side effects.

  6. Type of procedure for repeat Lasik– Depending on the type of first surgery and the residual bed thickness below the flap, we decide the type of repeat procedure. If enough corneal bed is available below the flap we can lift the same flap and perform the excimer laser ablation to correct the number. If not then we can consider an alternative procedure called Surface Ablation or PRK. In this procedure we do not raise the flap and instead perform laser on the surface of the cornea.
