What kind of myopia surgery is the best at present?

Myopia surgery can be divided into two categories: one is to correct myopia by laser cutting cornea (changing corneal curvature), and the other is to correct myopia by implanting intraocular lens without cutting cornea, which is called posterior chamber intraocular lens (ICL/TICL) implantation.

First, corneal laser surgery

At present, most myopia operations are corrected by laser ablation of cornea.

Second, ICL intraocular lens implantation

Also known as intraocular lens implantation, the principle is similar to implanting a pair of glasses in a safe part of the eye, thus achieving the purpose of correcting myopia. Clinically, it can be used to correct high or ultra-high myopia and astigmatism, or myopia and astigmatism that cannot be performed corneal refractive surgery for some reason. No need to cut or destroy corneal tissue, good reversibility (easy to take out and replace), no need to suture after operation. Suitable for correcting myopia of 50- 1800 degrees and astigmatism of 600 degrees. Postoperative vision was clear and recovered quickly.

Characteristics of ICL

0 1, unique crystal composition

Different from other lens intraocular lenses, the material of Evo ICL is Collamer, which is a unique body lens material. This special crystal material has higher biocompatibility than acrylic acid and silica gel. Evo -ICL is also foldable. Compared with other crystals, the incision needed in the operation is smaller.

02. The safety of the operation has been verified.

The safety and effectiveness of EVO-ICL implantation have been widely confirmed. More than 80,000 operations have been performed in more than 70 countries (USA, France, Germany, Japan, South Korea, etc.). ), and the FDA has passed strict clinical verification. Unlike corneal refractive surgery, EVO-ICL does not permanently change the structure of the eyeball, but is placed in the posterior chamber of the eye in a hidden way, just like the human lens itself to correct vision.

03, small incision.

Unlike other phakic intraocular lenses, EVO-ICL is foldable, so it can be implanted through a small surgical incision. Small incision is a technique that ophthalmologists are familiar with. ICL only needs an incision of 2.8 mm to 3.0 mm, while other phakic intraocular lenses approved by FDA need a surgical incision of 6.0 mm (more than twice). This small incision has little trauma, no need for suture and no astigmatism.

04. This operation is completely reversible and can be removed if necessary.

Evo ICL can be permanently implanted in the eye. However, if overcorrection or undercorrection occurs, or complications occur, or the patient's vision changes, the EVO-ICL can be removed or replaced by an ophthalmologist.
