High degree myopia is often associated to premature cataract.

The appearance or worsening of myopia in advanced age, is usually a sign that cataract is developing.

Cataract surgery can correct myopia via the implant of an intraocular lens with the appropriate strenght. Cataract surgery can also correct myopia and astigmatism.

In case of high degree myopia, cataract surgery requires specific precautions:

• it is best to avoid peribulbar anesthesia for major risks in case of high degree myopia
• the intraocular lens has to be carefully measured
• Retina has to be carefully checked before and after surgery, to avoid major risks in case of high degree myopia. Failing to take all necessary precautions, can result in an increased risk of retina detachment after cataract surgery.
