What about the ophthalmic medical instruments in BenQ?

Some patients may have blurred vision, glare and decreased night vision. There is also a keratoconus that protrudes outward because the cornea is too thin to resist intraocular pressure and is almost blind. Summarize the place beyond common sense in the sequelae of myopia surgery in one sentence: under normal circumstances, you can look at what you can't see clearly, but you can't see clearly after the operation. That is to say: visual quality/best visual loss. This kind of loss is permanent and cannot be solved by ordinary means such as glasses. The probability of this sequela is not small, which can be said to be an inherent drawback of surgery, but everyone has different degrees. After my investigation, I know that my symptoms are very mild, and more serious sequelae are widespread. Try not to do it as much as possible, and try several substitutes, such as light-frame lenses, contact lenses and rigid contact lenses (RGP). The worst case is better than permanent blindness and eye pain/dryness/high risk in the future.
