Background: Research and awareness on refractive solutions for presbyopia, commonly known as the “Curse of the 40’s,” is essential as a large population in the world suffer from vision impairments. Population-based surveys have shown that one billion people in the world are in presbyopic age. Purpose: Many structural and physiological changes occur in the eye with the onset of presbyopia, including the decrease in amplitude of accommodation. At present, various static and dynamic techniques have been attempted to give presbyopes good vision at near-, intermediate-, and far-viewing distances. The aim of the video is to familiarize the modern-day ophthalmologists to these modalities. Synopsis: In this video, we tried to summarize the indications and contraindications of presbyopic laser. Preoperative investigations like dominance testing and micro monovision testing are described. The role of neuroadaptation and patient counselling is emphasized. Static techniques described in the video include spectacles, contact lenses, surgical options like corneal inlays and onlays, corneal laser ablation, conductive keratoplasty, corneal implant lenses, INTRACOR and IOLs. Dynamic presbyopia correction (accommodative) is always surgical. This is split into lenticular (accommodating IOLs, piggyback, lens refilling, lentotomy) and scleral treatment (laser-assisted presbyopia reversal and scleral expansion bands). Highlights: The types of corneal laser ablation, which is otherwise very confusing, is elaborated in a step-wise manner here. The difference in approach of PresbyLasik (Nidek), Presbyond (Zeiss) - Laser Blended Vision, PresbyMax (Schwind), INTRACOR (Technolas) are explained with examples. Each approach has its pros and cons. Our challenge as a surgeon is to identify the best combination for the patient. This video illustrates the treatment options which can help break the curse of presbyopia. Online Video Link: https://youtu.be/rTxMIqMrgaw
