LASIK & Refractive Surgery

LASIK and other refractive surgeries are advanced procedures designed to correct common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These procedures aim to reduce or eliminate the need for glasses or contact lenses, providing patients with clearer vision and enhanced quality of life.

Understanding Refractive Errors

The eye focuses light onto the retina to produce clear images. Refractive errors occur when the shape of the eye prevents light from focusing correctly, resulting in blurred or distorted vision. Symptoms may include difficulty seeing distant or near objects, eye strain, headaches, and frequent changes in prescription glasses.

Indications for LASIK and Refractive Surgery

Refractive surgery is recommended for patients with stable vision who are typically over 18 years of age. Candidates should have healthy eyes without severe dry eye, infections, or other significant ocular conditions. A thorough preoperative evaluation ensures the procedure is suitable and tailored to individual needs.

Types of Refractive Surgery

Modern refractive surgery techniques are safe, precise, and minimally invasive. Common procedures include:

• LASIK (Laser-Assisted In Situ Keratomileusis): LASIK reshapes the cornea using a laser, allowing light to focus correctly on the retina. The procedure is quick, minimally invasive, and offers rapid visual recovery.
• PRK (Photorefractive Keratectomy): PRK is ideal for patients with thinner corneas. The laser reshapes the surface of the cornea, and the outer epithelial layer regenerates naturally. Recovery is slightly longer than LASIK, but outcomes are excellent.
• SMILE (Small Incision Lenticule Extraction): SMILE is a minimally invasive laser technique that removes a small lenticule of corneal tissue through a tiny incision, preserving corneal strength and promoting faster healing with less postoperative discomfort.

Preoperative Evaluation

Before surgery, a comprehensive eye examination is conducted, including measurements of corneal thickness, curvature, pupil size, and overall eye health. Advanced imaging and corneal mapping ensure precise treatment planning and optimal visual outcomes.

Procedure and Recovery

Refractive surgeries are usually performed under local anesthesia using numbing eye drops. The procedure typically lasts 15–30 minutes. Most patients notice improved vision within a day or two, although complete stabilization may take several weeks.

• Use prescribed eye drops to prevent infection and control inflammation.
• Avoid rubbing the eyes and exposure to dust or water during the initial healing period.
• Attend follow-up visits to monitor visual recovery and corneal healing.

Benefits of LASIK and Refractive Surgery

• Significant reduction or elimination of dependency on glasses or contact lenses.
• Rapid visual recovery and minimal discomfort.
• Improved quality of life in daily activities, sports, and work.
• Long-lasting results with proper eye care and regular follow-ups.

Safety and Success Rate

LASIK and other modern refractive surgeries are highly safe and effective. With advanced laser technology and careful patient selection, the majority of patients achieve 20/20 vision or better. Complications are rare and generally manageable, making these procedures a reliable choice for vision correction.
