Are intraocular lens really effective for high myopia rate patients (-15)? are there different types of these intraocular lenses for myopia? risky?

Yes: The power or "size" of the intraocular lens (iol) is determined similar to measuring shoe size-- by measuring the the length of the eyeball and the curvature of the cornea in the front of the eye. Even if you are very myopic, we can determine the appropriate power of an iol for your eye to give you clear distance vision. The established iols are very safe, but we are less sure about new ones.

Yes: Intraocular lens implantation after cataract surgery is being used frequently to correct different degree of myopia with good result. Implants may need to special order if it is a high degree of myopia. Surgical risk is the same as any other cataract surgery. For very high myopia, rate of retinal detachment after surgery is higher than average population.

Yes: Implant choices: Best intraocular (IOL) choice: Depends on if you want good reading, computer, distance vision OR all distances after surgery; if you have astigmatism (may need Toric IOL). If you want good reading, intermediate, distance VA, Multifocal or Crystalens may be option. Full answer: Cataract Surgery Options at eyedoc2020.blogspot.com.
