Classification of Presbyopia by Severity

There are close to two billion individuals globally living with presbyopia. In spite of its ubiquitous and progressive nature, there is no widely accepted, formal guideline or consensus statement on the classification of presbyopia by degree of severity. A panel of leading eye care professionals representing both optometrists and ophthalmologists convened virtually to discuss and document their combined assessments from the body of literature and clinical practice expertise in this commentary. In light of emerging therapies, classifying presbyopia by mild, moderate, or advanced severity may help provide consistency of diagnosis among eye care providers and may aid in managing patient expectations with different treatment options.
