Generally, patients under the age of 40 still read well without the use of glasses following the surgery. Patients over the age of 40 may need reading glasses for small print. Presbyopia is a term that refers to the natural weakening of the muscles that occurs in our early to mid 40s, causing us to need reading glasses. LASIK does not correct or prevent presbyopia. Should you fall into this age category, we will be happy to discuss monovision with you at your consultation. Monovision allows many patients the convenience of near and distance vision without the use of reading glasses.
