Ophthalmology defines the section of medical science that deals with anatomy, physiology, treatment and management of ocular diseases, whereas, optometry covers eyes and related structures, especially, vision and visual impairments caused by diseases or disorders. An ophthalmologist is specialist in medical and surgical eye problems, however, optometrists are licensed to prescribe, fit lenses and treat various eye diseases like myopia, viral or allergic conjunctivitis, eye infection, etc. through topical diagnostics and therapeutic drugs. Common ophthalmologic conditions include glaucoma, cataract, refractive errors, retinal degeneration, ocular inflammation, macular edema, blepharitis, dry eye syndrome and other ophthalmological disorders.
The most widely known and used optometric instrument is the contact lens - types include bifocal or multifocal, cosmetic and ortho-k, a gas permeable contact lenses also called “corneal reshaping contact lens”. For ophthalmological treatments, mostly known surgical procedures include cataract surgery for intraocular lenses, refractive surgeries for vision improvement such as laser or microkeratome under LASIK or ALK surgery.
With expanding elderly population, global optometric & ophthalmic diagnostics and treatment products/ services market is expected to display optimistic growth in perceivable future. Other factors contributing to this growth are increasing coverage for vision care and growing prevalence of chronic diseases. Glaucoma, cataract, and macular degeneration are the leading eye diseases which require medical or surgical procedure for treatment in ophthalmology segment. Another disease catching up pace is diabetic retinopathy, which is a diabetes induced blindness affecting aging population globally.
Currently, optometry market is highly dependent on changing healthcare practices, eye wear fashion trends and demographics, and is also highly fragmented with many players individually developing technologically advanced treatments and therapies. Increasing risk of various eye disorders is fuelling the growth of the global optometry market, whereas, low patient compliance is the biggest challenge. Few of the top companies operating in optometry market are Vision Care, Bausch and Lomb, Carl Zeiss, Hoya Corp, and among others.
