Today there are different options for correcting presbyopia by corneal laser procedure, but all of them have their benefits and compromises. The Monovision is a pseudoaccommodation procedure which works with an anisometropy of up to 2 D. The smaller the anisometropy is the faster a neuroadaptation will be achieved. There could be a decrease of binocularity. The monovision is not well supported by all patients, thus it is important to simulate this correction by contact lenses before surgery. The PresbyLASIK is a corneal multifocal solution for presbyopia correction for emmetropic, myopic and hyperopic eyes. It is a true presbyopia procedure where both eyes will be treated for far, intermediate and near. The disadvantage and compromise is that in some cases there could be a loss of uncorrected visual acuity. The corneal inlay is a solution for emmetropic, presbyopic patients who have a strong intention to read without glasses. The disadvantages could be some side effects as halo, glare, decrease of contrast and far vision. All procedures are potentially reversible in case the patient does not support the correction. An enhancement is possible for Monovision and PresbyLASIK.
