FEMTO - LASIK

Recovery Faster Than LASIK And Lesser Discomfort

How Femto LASIK Surgery Works: A Comprehensive Guide

Femto LASIK, or Laser-Assisted In Situ Keratomileusis, is an advanced form of laser eye surgery that is used to treat astigmatism, hyperopia, and myopia. Femto LASIK, in contrast to standard LASIK, offers higher safety and precision since it creates the corneal flap using a femto second laser rather than a mechanical blade. Here's a detailed explanation of how Femto LASIK surgery operates:

1. Pre-operative Planning, Counseling, and Assessment
Prior to the procedure, patients have a thorough eye examination. This comprises:

- Examine visual acuity to determine the extent of required vision correction.
- Measurement of Corneal Thickness: This makes that the cornea is sufficiently thick for the operation.
- Pupil dilation enables the retina and optic nerve to be examined by the ophthalmologist.
- Corneal Topography: Maps the cornea's surface curvature to identify anomalies.

Patient Preparation

In order to give the cornea time to revert to its natural form, patients are advised to cease wearing contact lenses several weeks prior to the procedure.
Patients should refrain from using lotions, moisturizers, cosmetics, or perfumes the day of the procedure.

2. The Femto LASIK Process

Step 1: Corneal Flap Formation

- Femtosecond Laser: To generate a thin, hinged flap on the surface of the cornea, the surgeon employs a femtosecond laser. This laser precisely separates the corneal tissue by emitting short bursts of light.
- Safety and precision: By enabling a thinner and more precise flap, this technique lowers the possibility of problems and speeds up the healing process.

Step 2: Cornea Reshaping

- Excimer Laser: The cornea is reshaped with an excimer laser following the flap's lifting. The laser uses the patient's prescription to eliminate tiny quantities of tissue.
- Custom Ablation: To improve visual outcomes, higher-order aberrations can be addressed with the excimer laser using custom ablation that is guided by corneal topography.

Step 3: Moving the flap around

Repositioning the Flap: Without using stitches, the corneal flap is carefully repositioned back onto the cornea. The ocular tissue can mend itself in situ because of its innate adhesive characteristics.

3. Immediate Aftercare and Post-Surgery Care

Observation: Patients take a brief break in the clinic while being watched.
Protective Eyewear: To avoid unintentionally scratching their eyes, they are given protective eyewear.

Follow Up

- Medication: In order to relieve dryness and avoid infection and inflammation, patients are prescribed eye drops in addition to artificial tears.
- Follow-Up checkups: Appointed checkups with the ophthalmologist are essential for tracking healing and guaranteeing the best possible outcomes.

Recovery Timeline

During the first 24 hours, patients should relax as their vision may be impaired. Steer clear of physically demanding tasks and closely adhere to post-operative care guidelines.
First Week: There is typically a noticeable improvement in vision. Keep taking your meds as directed, and try not to touch your eyes.
First Month: Stable Vision is attained by most patients. Frequent follow-up consultations facilitate progress monitoring.

4. Femto LASIK's Improved Safety and Precision Advantages

By creating flaps with more precision than mechanical blades, the femtosecond laser lowers the possibility of difficulties.

Tailored Care

- For improved results, individualized treatment regimens based on wavefront analysis and corneal topography address individual visual defects.

Quicker Recuperation

- The procedure's less invasiveness speeds up healing and lessens discomfort during the healing process.

Better Visual Results

- Higher-order aberrations can be corrected with Femto LASIK, improving total visual acuity and night vision.

5. Possible Hazards and Difficulties

Femto LASIK is usually safe and successful, however there are some possible dangers, such as:

- Dry eyes: Medication is typically able to relieve the frequent temporary dryness and pain in the eyes.

- Flap Complications: Although they are uncommon, problems with the corneal flap, including as dislocation or uneven healing, can happen.

- Undercorrection or Overcorrection: For some activities, patients may still require glasses or contact lenses.

- Halos and Glare: Some patients may have trouble seeing, particularly in dimly lit areas.

6. Suitability for Femto LASIK

Ideal Candidates

·        Adults over 18 with stable vision prescriptions.

·        Individuals with sufficient corneal thickness.

·        Patients without significant eye diseases or conditions that could affect healing

Candidates may not be eligible if they have certain medical issues, such as severe dry eye syndrome or autoimmune illnesses.
Because pregnancy and breastfeeding cause changes in hormones that influence the stability of vision, they are temporary contraindications.

In summary

Femto LASIK is a state-of-the-art surgery that has many advantages over standard LASIK, such as improved safety, accuracy, and reduced recovery times. Femto LASIK gives patients the chance to improve their quality of life and acquire better visual results by utilizing cutting-edge laser technology. To find out if Femto LASIK is the best option for your vision correction needs, schedule a comprehensive consultation with a skilled ophthalmologist, just like you would for any surgical surgery.
