Corrective eye surgery
What is corrective eye surgery?
Corrective eye surgery, also known as refractive surgery, is a surgical procedure designed to correct common vision problems such as nearsightedness, farsightedness, and astigmatism. The surgery works by reshaping the cornea, which is the clear, dome-shaped surface that covers the front of the eye. By reshaping the cornea, light entering the eye is properly focused on the retina, resulting in improved vision.
Types of corrective eye surgery
There are three main types of corrective eye surgery. They are:
1. LASIK (Laser Assisted In Situ Keratomileusis)
LASIK is the most common type of corrective eye surgery. The procedure involves using a laser to create a flap in the cornea which is then lifted to expose the underlying corneal tissue. The laser then reshapes the cornea, and the flap is placed back in position.
2. PRK (Photorefractive Keratectomy)
PRK involves using a laser to reshape the cornea without creating a flap. Instead, the surgeon removes the outer layer of the cornea before reshaping it with the laser. There is no flap created in this procedure.
3. SMILE (Small Incision Lenticule Extraction)
SMILE is the latest surgical technique designed to correct myopia. Rather than using a laser to reshape the cornea, SMILE uses a femtosecond laser to create a small incision in the cornea, through which a small disc of corneal tissue is removed. This alters the shape of the cornea, improving vision.
Who is a candidate for corrective eye surgery?
Corrective eye surgery is not suitable for everyone. The best way to determine whether you are a candidate for the surgery is to schedule a consultation with a qualified ophthalmologist. However, in general, suitable candidates for corrective eye surgery are:
1. Over the age of 18
2. Suffering from a stable vision problem
3. In good overall health
4. Not pregnant or nursing
5. Not suffering from certain eye conditions such as glaucoma or cataracts
The Procedure
The procedure for corrective eye surgery typically takes less than a 1/4 hour. Before surgery, the patient is given a sedative to help them relax. Local anesthesia is applied to the eyes to numb them. The surgeon then uses a laser or surgical blade to create a flap in the cornea. The surgeon then reshapes the cornea using an excimer laser. Once the cornea is reshaped, the flap is returned to its original position and allowed to heal.
Postoperative Care
After the surgery, the patient is required to wear a protective shield over their eyes for several days. They will be prescribed eye drops to help reduce inflammation and prevent infection. The patient is typically advised to avoid rubbing their eyes, swimming, or engaging in any strenuous activities that could affect the healing process. Patients may experience some discomfort in the first few days after surgery, but this typically subsides with time.
Benefits of Corrective Eye Surgery
Corrective eye surgery can provide significant benefits. Some of them are:
1. Improved Vision
The most obvious benefit of surgery is improved vision. Patients typically experience significant improvement in their visual acuity, allowing them to see clearly without the need for glasses or contact lenses.
2. Increased Quality of Life
Improved vision can enhance the quality of life of patients. They can enjoy activities they weren’t able to before and experience greater independence.
3. Cost-Effective
In the long run, corrective eye surgery can be a cost-effective solution to vision correction. The cost of the procedure is recovered over time from not purchasing eyeglasses or contact lenses.
4. Quick Recovery Time
Post-operative recovery time is usually quick for most patients. They can return to their regular activities within a few days after surgery.
In conclusion, corrective eye surgery is a highly effective solution for vision correction. The procedure can provide significant benefits to patients, such as improved vision, increased quality of life, and cost-effectiveness. Selecting the right type of surgery depends on various factors, and it is important to consult with a qualified ophthalmologist. But, in general, most patients who undergo the procedure recover relatively quickly and are highly satisfied with the outcome of their surgery.
