Femto-LASIK is a bladeless LASIK procedure, which is used to correct refractive errors. It is an approved treatment process. In this process, a femtosecond laser is used instead of an excimer laser. It is a painless and safer alternative for the ordinary LASIK.
It is a type of corneal refractive laser surgery and uses a femtosecond laser to reshape the cornea to correct the refractive error by forming a thin flap in the cornea. Some of the well-known benefits of this procedure include bladeless treatment, quick recovery, and renowned precision.
- In the Femto-LASIK procedure, the top layer of the cornea is opened circularly like a small lid and then folded aside.
- This cornea lid is known as the flap. The conventional LASIK procedure employs a blade and a microkeratome to form the flap. However, the Femto-LASIK uses a femtosecond laser for the formation of the flap.
- The laser beam discharges energy at the exact, defined depth of the cornea. This leads to the creation of numerous bubbles within the determined area.
- The LASIK specialist then detaches a thin corneal lamella from the same area. The corneal lamella is detached by gently cutting the tissue bridges between the gas bubbles.
- The specialized technique allows the ophthalmologist to form a thinner flap safely.
- In rare circumstances, the Femto laser may make a miscut, but this is virtually harmless. Even if the first cut using the Femto laser is not perfect a subsequent cut can be performed immediately with ease.
- The miscut does not cause any kind of damage because the cornea absorbs the tiny bladders caused by the Femto laser, and the tissue grows together again.
- Finally, the flap is repositioned, allowing it to heal and adhere naturally without the use of any stitches.
The Femto-LASIK treatment is preferred as it can correct vision impairments more accurately than LASIK. The wavefront-guided methods are better suited to correct the unfavorable results of the other LASIK treatments. This method is also the preferred choice for first-time surgery. The technological advancements of the Femto-LASIK treatments achieve high-standard results with precision.
Patients have to fit the criteria to be eligible to receive treatment.
The requirements include:
- The patient must be above the age of 18.
- The patient’s power of spectacles must be stable for at least two years.
- The patient must have a minimum corneal thickness of 470 microns.
- The patient must have a normal corneal topography.
- The patient must have good ocular health.
- The patient must not be pregnant or breastfeeding.
After the laser procedure is completed, the ophthalmologist will recommend some aftercare measures.
The after-surgery recommendations include:
- Make sure to avoid rubbing the operated eye.
- It is crucial to wear an eye shield while sleeping to avoid moving the flap. This should be continued for one week to fasten the healing process and to avoid discomfort.
- Follow the surgeon’s guidelines and regularly use the prescribed eye drops to prevent infection and control dryness.
- Strenuous contact sports like swimming, football, and basketball have to be avoided for two weeks.
