To this day, a small percentage of people who are very nearsighted (myopic) do not qualify for laser vision correction (e.g., LASIK) either because they have a very high prescription (>12-13D) and / or they have a very thin cornea which makes LASIK quite risky (they may develop irregular astigmatism (ectasia) afterwards).
Needless to say, in the past, people in this situation had no choice but to wear their very thick “coke-bottle” glasses or abuse their (usually) hard contact lenses. Today, there is a great option for people with this predicament as there are implantable contact lenses that can be placed inside the eye!
The Visian ICL is a tiny clear lens that can be placed in the eye in a matter of a few minutes with no sedation, and without the need for any sutures. This technology has been approved by the FDA since 1995, and since then, thousands of people with very high myopia have enjoyed clear vision without the need for glasses or contact lenses whatsoever.
