The LASIK procedure is the right answer for most patients who are considering refractive surgery to improve their vision. However, in patients with higher degrees of nearsightedness or farsightedness, the cornea may be too thin to allow full refractive correction.
In these cases, surgical implants may be the best alternative. These special devices are placed in the eyes to improve their focusing ability.
