1.Simple surgery, safe and quick: small surgical incision, same day surgery, same day discharge, and the crystal can be easily removed after surgery without changing the structure and shape of the eye tissue. 2.Wide correction range, no damage to the cornea: It can be used to correct a wide range of myopia, hyperopia and astigmatism without removing the cornea or destroying corneal tissue, without surgical suturing, and with excellent visual quality. 3, reversible, can be removed at any time: If the patient’s vision has changed significantly and the ICL worn is no longer suitable, it can be removed or replaced at any time. It can also be repaired with ordinary frame glasses or contact lenses. 4. Convenient post-operative care: ICL is designed for long-term implantation inside the eye without maintenance. 5.No foreign body sensation and good migration: After ICL implantation, no foreign body sensation will be felt in the eye and the implant will not be combined with any tissue structure, so the solid migration is good. 6. Scientific design, practical and beautiful: ICL is implanted in the posterior chamber behind the iris and is fixed in the ciliary sulcus with a unique double-sided baking design, which does not touch the crystal or the iris and cannot be seen from the outside by outsiders or the eye itself, achieving perfection in cosmetology. However, any surgery is damaging, and refractive IOL implantation in the eye may also cause complications such as elevated intraocular pressure and cataracts, so it is important to first select an experienced surgeon for the examination and surgery, and to have regular follow-up examinations at the ophthalmology department after the surgery to ensure long-term safety of the eye after the surgery. Complications of refractive lenses can be detected and treated early through regular post-operative annual checkups, so it is not scary.
