Generic clinical notes don't have fields for IOL calculations, RNFL thickness, or intravitreal drug dosage. An ophthalmology clinical session isn't a free-text note with a few measurements added. A cataract session requires biometry results, IOL selection, and phacoemulsification technique documentation. A glaucoma session requires IOP, disc grading, and OCT RNFL values structured for longitudinal comparison. A retina session requires intravitreal drug name, batch, dose, and injection site per eye. WIO CLINIC's ophthalmology session interface provides structured forms for each sub-specialty — General Exam, Cataract, Glaucoma, Retina, and Refractive Surgery — with every field clinicians actually fill in.
