PresbyLASIK uses the principles of LASIK surgery to create a multifocal pseudoaccommodative corneal surface. It increases corneal asphericity to increase the depth of field, allowing for improved near focus. There are two predominant presbyLASIK techniques: peripheral presbyLASIK and central presbyLASIK. Peripheral presbyLASIK creates a myopic ablation in the mid-peripheral cornea to allow for near vision. Central presbyLASIK creates a central ablation that focuses for near vision. A third technique, termed micro-monovision presbyLASIK, combines presbyLASIK with monovision, where the dominant eye is corrected as an emmetrope for distance, while the non-dominant eye is corrected slightly myopic in either a central presbyLASIK or peripheral presbyLASIK ablation pattern. We present a brief review of results from papers and posters on presbyLASIK published in the recent 5–6 years. Two newer techniques for ablation patterns currently being investigated, isovision and prebyond, are also briefly discussed.
