Introduction

Laser surgery can treat myopia. Currently, the main types of lasers used for correcting myopia are excimer laser and femtosecond laser. Excimer laser surgery is further divided into photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). Candidates must be at least 18 years old, have stable refractive status for over two years, and pass all required examinations before considering corneal refractive surgery.

In today's society, laser technology is considered relatively advanced. Some people enjoy using electronic devices and often stay up late, which may lead to myopia (nearsightedness). They may consider laser surgery as a treatment option. Can laser surgery correct myopia?

Can Laser Surgery Treat Myopia?

Yes, laser surgery can treat myopia. Currently, two main types of lasers are used for correcting myopia: excimer lasers and femtosecond lasers. Excimer laser procedures include photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK). Candidates must be at least 18 years old, have stable refraction for over two years, and pass comprehensive eye examinations before being considered eligible for corneal refractive surgery. The excimer laser procedure involves creating a corneal flap and then reshaping the cornea with an excimer laser to correct refractive error.

Femtosecond laser surgery is further divided into semi-femtosecond and full-femtosecond procedures. Full-femtosecond laser surgery is the latest technique, in which the femtosecond laser performs two scans within the corneal layers to create a lens-shaped piece of tissue. This lens is then removed through a small incision at the edge of the cornea, completing the procedure and effectively treating myopia.

You can visit a hospital to undergo a detailed eye examination so that a doctor can recommend the most suitable treatment based on your individual condition. It's also important to reduce screen time on electronic devices such as smartphones and tablets, get adequate rest, and ensure sufficient sleep. We hope this information has been helpful. Wishing you good health and happiness!

What does vision 4.5 correspond to?

Visual acuity of 4.5 on the logarithmic visual chart corresponds to 0.3 on the decimal visual chart, indicating insufficient clarity when viewing distant objects. This may result in blurred or double vision when looking at faraway items. In daily life, one might need to move closer to see things like blackboards or road signs clearly. This condition is commonly associated with refractive errors such as myopia or astigmatism.

What should I do if my nearsightedness suddenly worsens?

If nearsightedness suddenly worsens, it is important to promptly undergo an eye examination to reassess vision, rule out eye diseases, adjust visual habits, improve the visual environment, and supplement nutrients beneficial for eye health, so as to avoid delaying diagnosis and treatment of potential problems. If accompanied by symptoms such as eye pain, distorted vision, light sensitivity, or excessive tearing, immediate medical evaluation is recommended. A professional eye exam can accurately determine changes in myopia degree and distinguish between true myopia and pseudo-myopia.

How to Get Rid of Myopia Glasses

To get rid of myopic glasses, common methods include laser surgery, implantable intraocular lenses, orthokeratology (corneal reshaping lenses), vision training, and controlling the progression of myopia. Eligible individuals may choose laser surgeries such as SMILE or LASIK, which adjust the corneal shape to correct refractive errors, allowing light to focus accurately on the retina. After surgery, clear vision can be achieved without the need for glasses.

What is 500-degree myopia in terms of decimal visual acuity?

If an individual has strong accommodative ability of the eyes, even with 500 degrees of myopia, they may achieve around 0.2 visual acuity during a standard eye chart test by relying on the eye's natural accommodation, barely recognizing the larger optotypes on the chart. However, distant details still appear blurry, and prolonged visual tasks can easily cause eye strain. Therefore, they still need corrective devices to improve their vision.

What is the highest degree of myopia?

From the perspective of common clinical classifications, myopia exceeding 600 degrees is considered high myopia, and over 1200 degrees is classified as very high myopia. Although these conditions are relatively rare in the general population, the number of individuals with high myopia has been gradually increasing due to changes in eye usage habits. Most patients with high myopia can maintain normal daily lives through appropriate correction, provided that no severe structural abnormalities have developed in the eye.

How to recover from myopia in children's eyes

Children's myopia cannot be reversed. The key to improvement lies in controlling the progression of myopia, which can be achieved through scientifically prescribed eyeglasses, developing good eye-use habits, increasing outdoor activities, performing standardized eye exercises, and adjusting dietary patterns. These interventions help prevent myopia from progressing to high myopia. If you notice symptoms such as blurred vision or squinting in your child, it is recommended to seek timely medical evaluation and refraction testing.

How to restore normal vision for right eye myopia

Methods that may help improve or control myopia in the right eye generally include scientifically wearing corrective glasses, using orthokeratology lenses, performing regular eye relaxation exercises, adjusting visual habits, and conducting routine vision monitoring. Scientifically wearing corrective glasses: Obtain a professional eye examination at a qualified institution to determine the accurate prescription, and select appropriate single-vision or progressive multifocal glasses to correct refractive errors, ensuring clear vision and preventing myopia progression caused by blurred eyesight.

Is eye massage helpful for myopia?

For individuals with myopia who experience eye fatigue symptoms such as eye pressure, dryness, and soreness due to prolonged near-work, gently massaging acupoints around the eyes (such as the temples and Jingming points) can promote blood circulation in the eyes, relax the surrounding muscles, alleviate fatigue, and provide temporary comfort. This may help prevent further indirect impact on vision caused by worsening eye strain, but it cannot alter the structure of the eyeball or reduce the degree of myopia.
