Most of the people working on computers, are nowadays experiencing issues with their eyes like Hyperopia and astigmatism. You see faraway things more clearly, but closer things are blurry. People who's been wearing glasses for years are tired of them and are looking for ways to get rid of them. If that's the case with you ,let us understand Lasik and see if it's going help you with your eye problems.
LASIK (Laser-Assisted in Situ Keratomileusis) is a widely performed eye surgery designed to correct refractive vision issues such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. By reshaping the cornea—the transparent, dome-shaped surface that covers the front of the eye—LASIK enables light entering the eye to be properly focused onto the retina, resulting in clearer vision.
Why Consider LASIK Surgery?
LASIK is often chosen by individuals seeking to reduce or eliminate their dependence on corrective lenses. It offers several advantages:
High Success Rate: Approximately 96% of patients achieve their desired vision outcomes post-surgery.
Minimal Discomfort: The procedure is generally painless, with most patients experiencing only slight discomfort during recovery.
Quick Recovery: Many individuals notice improved vision within a few days and can resume normal activities shortly thereafter.
Long-Term Benefits: While vision changes can occur with aging, LASIK provides lasting correction for many individuals.
Potential Risks And Side Effects of LASIK Surgery
As with any surgical procedure, LASIK eye surgery carries certain risks and potential side effects:
Dry Eyes: Temporary dryness is commonly seen; however, for some, it may persist.
Visual Disturbances: Some patients report glare, halos, or difficulty seeing at night.
Under correction or Overcorrection: In some cases, the desired vision correction may not be achieved, necessitating further treatment.
Ectasia: A rare condition where the cornea becomes progressively thinner and bulges forward, potentially leading to vision loss.

Pre-operative Evaluation Required For LASIK Vision Correction
Before undergoing LASIK, a thorough eye examination is essential to determine candidacy
Age: Candidates should be over 18 years old. If you are below 18, vision correction with LASIK is not suggested.
Stable Prescription: Vision prescriptions should remain unchanged for at least six months.
Corneal Thickness: Adequate corneal thickness is necessary to safely perform the procedure.
Eye Health: Conditions such as glaucoma, cataracts, or keratoconus may disqualify an individual from LASIK.
The LASIK Procedure
The LASIK surgery typically involves the following step:
1. Preparation- Numbing eye drops are administered to ensure comfort.
2. Flap Creation- A thin flap in the cornea is created using a microkeratome or femtosecond laser.
3. Reshaping the Cornea- A laser is used to remove microscopic amounts of corneal tissue, reshaping it to correct the refractive error.
4. Flap Repositioning- The corneal flap is repositioned, serving as a natural bandage.
The entire procedure usually takes about 20 minutes per eye.
Postoperative Care And Recovery.
Post-surgery, patients should adhere to the following guidelines:
Rest: Allow the eyes to heal by avoiding strenuous activities.
Medication: Use prescribed eye drops to prevent infection and inflammation.
Follow-Up Appointments: Attend all scheduled check-ups to monitor healing progress.
Protective Measures: Wear protective eyewear as recommended, especially during sleep, to prevent accidental rubbing.
Frequently Asked Questions
1. Is LASIK suitable for everyone?
Not everyone is an ideal candidate. Individuals with certain health conditions, such as autoimmune disorders or uncontrolled diabetes, may not be suitable candidates.
2. How long does the LASIK procedure take?
The LASIK procedure typically takes about 20 minutes per eye.
3. Will I need glasses after LASIK?
For most individuals, laser eye surgery effectively enhances their distance vision to a level that is comparable to or even superior to that achieved with corrective lenses. Following the procedure, patients can generally expect to read as clearly as they would with their optimal pair of glasses or contact lenses during a post-operative eye examination.
Nonetheless, the probability of achieving complete independence from glasses or contact lenses post-surgery is influenced by several key factors:
- The strength of your prescription and the specific type of refractive error (such as myopia, hyperopia, or astigmatism)
- The expertise of your surgeon and the laser technology utilized
- Your age
LASIK surgery provides a permanent solution for vision issues like myopia (nearsightedness), often resulting in the immediate cessation of the need for glasses or contact lenses after the operation.
It is important to note that LASIK surgery does not safeguard against age-related eye conditions nor does it rectify certain refractive errors that may arise from corneal thickness.
4. Are there alternatives to LASIK?
Yes, alternatives include PRK (Photorefractive Keratectomy), SMILE (Small Incision Lenticule Extraction), and implantable contact lenses
Conclusion.
LASIK eye surgery presents a promising solution for individuals seeking to reduce their dependence on glasses or contact lenses. With advancements in technology and surgical techniques, LASIK offers high success rates and quick recovery times. However, it's crucial to consult with a qualified ophthalmologist to determine if LASIK is the right choice based on individual health conditions and vision needs.
