Myopia and astigmatism evaluation
Treatment options in Shanghai

LASIK reshapes the cornea with a laser and involves creating a flap. SMILE is another corneal refractive approach, discussed in Fudan's specialist training materials as small-incision lenticule extraction. The names alone do not reveal which is appropriate for your cornea or prescription. Ask the surgeon what tissue is changed, which measurements determine suitability and why one option is recommended over another. Avoid translating a shorter laser-treatment time into a promise of safer surgery, better night vision or quicker readiness for every activity.

A phakic intraocular lens is placed inside the eye while the natural lens remains. This is different from replacing the natural lens, as in cataract surgery or a lens-exchange procedure. Ask which operation is actually proposed and how it compares with corneal treatment and continued optical correction. A phakic implant is intended to remain in the eye. Although it can be surgically removed, the FDA cautions that return to the previous vision or eye condition cannot be guaranteed. Calling an implant removable does not make surgery consequence-free.

Important questions include whether the prescription is stable, whether the cornea is suitable and whether dry eye or another eye condition changes the balance. Discuss prior eye surgery, medicines and health conditions that might affect healing, as well as contact sports or work requirements. Do not stop treatment independently to qualify for a procedure. A recommendation to treat an eye-surface problem first, obtain more information or remain with glasses can be a useful outcome. Ask your Shanghai eye team to apply these assessment points to your measurements and the procedure it proposes.
