PIE or Lasik – that is the burning question question for people above 45 years of age.
This article will define the two procedures, discuss benefits of each, look at advantages and disadvantages of PIE and Lasik and finally will help you discover which is the best procedure for people who have spens more than 4-5 decades on earth.
Most people are familiar with Lasik eye surgery. Lasik is a method of vision correction surgery using laser technology to reshape the eye. Lasik on the hand is a corneal procedure and there is no entry into the eye. So it can be done in a Lasik suite. The recommended age is above 18 years. The corneal shape and thickness distribution has to be normal as well as sufficient for the treatment. IF there is shortage of tissue superlasik or superficial Lasik may be considered. ICL or Implantable collamer lens may be the only option in severe nearsightedness. All these three procedures are static or monofocal procedures. That is they set the power of the eye to a set distance usually infinity. If the eye can change the shape and power of the natural lens than the eye can see middle and near. That means it works well for people under forty-five years of age. Therefore, these are the procedures of choice in the age group 18 to 45 years of age.
The story changes above 45. Only a handful of people would qualify for Lasik eye surgery. These would be the low hyperopes or people wanting blend vision. Of course, they should not be susceptible for dry eyes.
PIE is a newer technology. PIE is short for presbyopia implant in eye. This is a short painless procedure where the contents of the natural lens are exchanged for a manmade plastic lens. The procedure is performed under sterile conditions in an ambulatory surgery center. The implant is made of acrylic or silicone which are very well tolerated by the eye. So naturally this question gets posed very often “Doc which is the better option for me – Lasik or PIE?” For the rest PIE is the best. It allows a person to see at different distances with each eye. Once the procedure is done in both eyes it yields natural binocular vision. And wait there is more. This is a permanent procedure. The patient undergoing PIE will never develop cataracts. PIE does not induce dry eyes. It is also superior to monovision.
Few surgeons are adept with the nuances of this method of permanent vision procedure called PIE. Hence you may not have come across much info till now. Rest assured if you were born before 1975 this is the procedure of choice for you.
