Introduction
Common correction methods for astigmatism generally include wearing eyeglasses for astigmatism, wearing toric contact lenses, undergoing corneal laser surgery, implanting toric intraocular lenses, and wearing orthokeratology lenses. Wearing eyeglasses for astigmatism: This is the most basic correction method, which involves incorporating the appropriate astigmatism prescription and axis into the lenses to precisely adjust light refraction, thereby improving blurred vision and double imaging.
Common methods for correcting astigmatism generally include wearing eyeglasses for astigmatism, wearing toric contact lenses, undergoing corneal laser surgery, implanting toric intraocular lenses, and wearing orthokeratology lenses. Detailed explanations are as follows:
1. Wearing eyeglasses for astigmatism: This is the most basic correction method. By incorporating prescribed astigmatism power and corresponding axis into the lenses, these glasses precisely adjust light refraction to improve blurred or double vision. Suitable for patients of all ages with astigmatism, especially children, elderly individuals, or those who prefer not to undergo surgery. These glasses are relatively affordable and easy to replace.
2. Wearing toric contact lenses: Available in rigid and soft types, these lenses better conform to the corneal shape, reducing visual distortion and limited field of view that may occur with eyeglasses. Rigid gas-permeable toric lenses offer higher correction accuracy and are suitable for patients with high astigmatism. Soft toric contact lenses provide greater comfort and are ideal for mild to moderate astigmatism. Proper daily cleaning and regular replacement are essential.
3. Corneal laser surgery: This procedure uses a laser to reshape the corneal stroma, adjusting the cornea's refractive state to correct astigmatism. Common procedures include LASIK and SMILE. It is suitable for patients aged 18 years or older with stable astigmatism. Vision can be significantly improved long-term without the need for glasses after surgery. However, adequate corneal thickness and good ocular health are required, necessitating comprehensive preoperative evaluation.
4. Implantation of toric intraocular lenses: Primarily used for patients with cataracts combined with astigmatism. During cataract surgery, a toric intraocular lens that corrects astigmatism is implanted, treating both cataracts and astigmatism simultaneously. This approach allows for rapid visual recovery and is ideal for middle-aged and elderly patients seeking surgical vision correction.
5. Wearing orthokeratology (OK) lenses: These are worn overnight and gently reshape the front surface of the cornea through controlled pressure. Clear vision can be achieved during the day without wearing corrective lenses. Additionally, they may help control myopia progression associated with astigmatism in adolescents. Fitting must be performed at a professional eye care facility, and strict lens hygiene and maintenance are required. They are suitable for children aged 8 years and older with low degrees of astigmatism.
Prior to selecting a correction method for astigmatism, a comprehensive eye examination at a reputable ophthalmic institution is necessary to determine the degree and axis of astigmatism and assess overall eye health. If sudden vision loss, eye pain, or other discomfort occurs, prompt medical attention is recommended to adjust the correction plan accordingly.
