Is Lens Replacement Surgery a permanent fix?

Unlike glasses that need to be changed every 2-3 years at great expense, intraocular lenses (IOLs) are designed as a permanent fix, meaning you will not need to have these changed for the remainder of your life. Successful surgery results in not requiring any glasses at all after the rehabilitation period.


Of course the permanent success of the procedure is dependent upon the suitability of the candidate in the first instance and if there are any pre-existing eye conditions which may affect the final visual outcome.

What is the difference between Laser Eye Surgery and Lens Replacement Surgery?

Laser Eye Surgery usually refers to corneal refractive laser surgery (LASIK or PRK). This sort of laser surgery is usually reserved for younger patients with myopia (shortsightness), astigmatism or both. It is not recommended once you are over 40 years of age and have Presbyopia.

Lens Replacement Surgery may or may not be performed using lasers. Most commonly Lens Replacement Surgery is done with the aid of ultrasound power (phacoemulsification) which is the most common technique used in cataract surgery. Occasionally this surgery may be performed with the aid of femtosecond laser.
