Refractive surgery is an exciting option to correct vision problems and improve your quality of life by reducing or eliminating the need for glasses or contact lenses. This guide will provide you with an overview of refractive surgery, the different types of procedures, the preoperative and postoperative process, as well as the benefits and important considerations.
-
What is reflactive surgery?
Refractive surgery is a set of surgical procedures designed to correct vision problems such as myopia, hyperopia, astigmatism and presbyopia. These procedures reshape the cornea or implant intraocular lenses to improve the way light is focused on the retina.
-
What are the types of refractive surgery?
- LASIK (Laser Assisted In Situ Keratomileusis): Involves creating a flap in the cornea, reshaping the underlying corneal tissue with a laser, and then repositioning the flap.
- PRK (Photorefractive Keratectomy): The superficial layer of the cornea is removed before reshaping the corneal tissue with a laser.
- LASEK (Laser Subepithelial Keratectomy): Similar to PRK but with a thin flap on the corneal epithelium.
- Intraocular Lens Implants: Artificial lenses are placed inside the eye to correct vision, especially in cases of presbyopia.
-
What is the preoperative process of reflactive surgery?
- Consult with a specialized ophthalmologist: Evaluate if you are a candidate and discuss your expectations.
- Comprehensive eye exam: Evaluates your eye health, prescription and corneal shape.
- Discussion of risks and benefits: Understand the possible results and risks.
-
What is the process of reflactive surgery?
- Preparation: Anesthetic drops can be administered to the eyes.
- Surgery: Depending on the procedure chosen, a flap is created or the cornea is reshaped with a laser.
- Duration: The surgery is usually quick, generally about 15-30 minutes.
-
Postoperative recovery from reflactive surgery
- Rest and care: Rest after surgery and follow medical instructions.
- Symptom control: There may be temporary discomfort such as dry eyes or sensitivity to light.
- Follow-up: Schedule follow-up appointments with your ophthalmologist to evaluate your progress.
-
What are the benefits of refractive surgery?
- Improved vision: Can reduce or eliminate dependence on glasses and contact lenses.
- Greater comfort: You will enjoy greater comfort in daily activities.
-
Important considerations of reflactive surgery
- Candidacy: Not everyone is a candidate for refractive surgery. It will depend on your eye health and prescription.
- Risks: Although it is generally safe, there are risks such as infections or temporary side effects.
-
Informed decision making about reflactive surgery
Talk openly with your ophthalmologist, ask all necessary questions and fully understand the procedure before making a decision.
-
Long-term results:
The results of reflactive surgery are usually long-lasting, but may vary depending on the individual. Some people may require retouching.
Remember that each individual is unique and that the decision to undergo refractive surgery should be based on a thorough medical consultation. A specialized ophthalmologist will be your best guide in determining if you are a good candidate and which procedure is right for you.
