Eye surgery is an important and advanced area of medical science for those with vision problems, such as myopia, hyperopia, and astigmatism. Surgery to correct vision is an interesting option as it not only helps resolve vision issues but also reduces reliance on glasses or contact lenses, enhancing the quality of life by providing more comfort and safety.
6 Options and Types of Eye Surgery
Currently, there are several methods of eye surgery, each with its own differences:
1. PRK (Photorefractive Keratectomy) PRK is a technology for vision correction that uses an Excimer Laser directly on the cornea’s surface without cutting the corneal layer first. Instead, it simply removes the epithelial layer, either using medication or modern laser technology called TransPRK.
Advantages: The cornea remains intact with no seams, making it strong and suitable for those with thin corneas or occupations at risk of eye trauma, such as athletes or military personnel.
Limitations: Higher irritation in the eyes compared to other methods, necessitating rest for 3-5 days post-treatment.
2. LASIK (Laser-Assisted In Situ Keratomileusis) This method also uses an Excimer laser but employs a blade to open the top layer of the cornea and then applies the laser to the inner cornea before closing the top layer back.
Advantages: Quick recovery with less eye irritation.
Limitations: Must avoid trauma or rubbing the eyes for the first month; may experience dryness, which can be alleviated with artificial tears.
3. Femto-LASIK Femto-LASIK is a new LASIK technique using a Femto-second laser to open the corneal layer, providing more precision and safety than blade methods. Recovery is quick with minimal irritation, and care principles are similar to traditional LASIK.
4. ReLex (Refractive Lenticule Extraction) This method utilizes a Femto-second laser to cut within the cornea and creates a small hole to remove calculated corneal tissue, improving vision.
Advantages: Small incision, less irritation, and stronger cornea.
Limitations: May initially experience light scattering that improves over time.
5. Phakic IOL (Phakic Intraocular Lens) This technique involves inserting a lens between the cornea and the natural lens of the eye to adjust light refraction, improving vision (e.g., ICL, IPCL).
Advantages: Can correct very high myopia (>10 diopters), a limitation of traditional LASIK.
Limitations: Requires detailed examination of eye structure, particularly ensuring enough space for lens insertion.
6. Refractive Lens Surgery (RLS) RLS involves removing the natural lens that causes vision problems and replacing it with a custom-made intraocular lens using computer technology to calculate vision requirements.
Duration: The surgery takes about 10-15 minutes, and significant improvement in vision can be noted as soon as one day post-surgery.
As you can see, current eye surgery technologies offer a variety of methods, each with its advantages and limitations. If you have vision problems and are considering corrective surgery, consult a specialized ophthalmologist for a thorough evaluation and guidance before making a decision at Phyathai 2 Hospital Eye Center.
