Ophthalmologist analysis: Is myopia wearing glasses or surgery?

With the popularity of electronic products, increased learning burdens, and reduced outdoor time, myopia or other refractive errors (including hyperopia and astigmatism) have become the most common eye diseases. Defiant optic ophthalmologists tell you that in the event of refractive errors, there are many ways to correct them. As for which method to choose, it depends on the individual.

Wear glasses to follow the doctor's advice

There are a wide variety of glasses, such as wearing simple frame glasses, contact lenses that are more convenient to wear in the eyes, and keratoplasty lenses that can alleviate myopia in young people. How to choose glasses in the end? Experts in-depth analysis:

First of all, the choice of frame glasses is convenient to assemble, and the one-time cost is low, but the life is inconvenient and the exercise is inconvenient. If the fitting is unprofessional, wearing it for a long time will cause eye deformation. Secondly, the soft contact lens has less visual distortion than the frame glasses, and has a wider field of view, but the correction range is limited, the astigmatism correction effect is poor, and long-term wear may cause complications such as corneal edema and dry eye, and the wearing method is improper. It can cause inflammation of the cornea and conjunctiva.

Currently popular hard high oxygen permeability contact lenses (RGP) improve oxygen permeability, while ensuring good wettability and anti-sedimentation, can correct myopia within 2200 degrees, astigmatism within 600 degrees; cause a small chance of corneal infection, High security. However, it is necessary to pay attention to the care of the lens and the care of the eyes during use.

There is also a Ortho-K CL for children and adolescents. This is a highly oxygen-permeable and shape-sensitive contact lens that gently reshapes the corneal epidermis. It only needs to be worn at night and not worn during the day. Glasses can also get clear vision. Wearing it for a long time can effectively reduce the effect of deepening the myopia of teenagers.

Laser myopia surgery is good

After more than 20 years of development, myopia surgery has reached a very high level, generally suitable for those who are 18 years old or older and whose myopia status is no longer deepened. Laser surgery to correct myopia is a large range, can reduce myopia degrees at one time, can avoid the inconvenience and care of wearing frame mirrors or contact lenses.

Ophthalmologists have summarized the following three common surgical methods:

The first type is ordinary LASIK surgery. The corneal flap is made in the corneal stroma with a microkeratome, and then treated with an excimer laser to achieve the purpose of correcting refractive error. Although the operation time is short, the postoperative response is better, and the price is relatively cheap, but it is not suitable for patients with too high a degree.

The second is femtosecond laser LASIK surgery, which uses femtosecond laser instead of mechanical lamellar knife to make corneal flap, and then uses excimer laser to treat it, to achieve the purpose of correcting refractive error, increasing the safety and predictability of surgery. Sex, greatly reducing the risk of surgery. The disadvantage is that the cost is relatively high and the requirements for the machine and the operator are higher.

The third is full femtosecond laser myopia surgery. Full femtosecond laser myopia surgery is currently the most advanced corneal refractive surgery in the world, without the need to make a corneal flap. When the laser corrects ametropia, it does not use a knife at all. It can use its high precision, high power and high resolution to make the cells between the corneal layers of the same thickness decompose and expand to make a uniform corneal flap. The cost of this type of surgery is relatively high and is not suitable for patients above -10.00D.
