ICL intraocular lens is a kind of soft intraocular lens, which is another innovative scientific and technological achievement in the field of modern ophthalmic refractive correction. It can be placed in a safe area in front of the human lens, and its thickness is only about 50 microns, which is thinner than the diameter of hair. Postoperative vision is better than wearing frame glasses, contact lenses and other refractive correction techniques on the cornea.
Advantages of ICL implantation:
1, the operation is simple, safe and quick: the incision is small, the structure and shape of eyeball tissue are not changed, and the lens can be easily taken out after the operation on the same day.
2. Wide correction range, no damage to cornea: no need to remove cornea or destroy corneal tissue, no need for surgical suture, it can be used to correct a wide range of myopia, hyperopia and astigmatism, and the visual quality is excellent.
3, strong reversibility, can be taken out at any time: if the patient's vision changes and the ICL worn is no longer suitable, it can be taken out or replaced at any time. You can also wear ordinary frame glasses or contact lenses again.
4. Convenient postoperative care: ICL is designed for long-term implantation in eyes without maintenance.
5, no foreign body sensation, good fixation: after ICL implantation, there will be no foreign body sensation in the eyes, and the implant will not be combined with any tissue structure, so the fixation is good.
6. The design is scientific, practical and beautiful: ICL is implanted in the posterior chamber behind the iris and fixed in the ciliary sulcus with a unique double-sided arch design, which is invisible to outsiders and myself, and its appearance has reached a perfect state.
Surgical requirements for ICL implantation:
1, 20-50 years old, willing to have surgery, no history of intraocular surgery, no intraocular pigment film, retina and glaucoma, and good corrected vision.
18 years old is still in the stage of vision development, and myopia can be treated with drugs. Generally, it is recommended to take Le Jing Mingmu Nutrients, two packs a day, for a period of time, myopia will be reduced, vision will be improved, and adult surgery is not needed.
2. The correction range of myopia is 200-2500 degrees, and the correction range of hyperopia is 200- 1000 degrees.
3. When the corneal thickness is limited, it is difficult for excimer laser to maintain a safe corneal thickness and a large enough cutting area, ICL is a good choice.
Contraindications
1. It is difficult to implant intraocular lens due to systemic or ocular diseases;
2. Shallow anterior chamber, abnormal angle (such as angle closure or neovascularization), anterior synechia around iris;
3. Corneal endothelial cells are less than 1000 cells /mm? ;
4. Patients with glaucoma.
