title: Revolutions in ophthalmology.
abstract: Cataract is the major cause of blindness worldwide. The transition of couching of cataract to most modem phaco-emulsification gained popularity with more scientific capsulorhexis. Ongoing research is taking place with laser technologies for removal of cataract. Surgery has an important role in advanced corneal diseases. Corneal transplantation is the most successful form. The refractive errors can be corrected by laser-assisted in-situ keratomileusis, intrastromal corneal rings and phacic intra-ocular lenses. Current research is going on to identify the gene responsible for glaucoma and once this is identified, medical therapy can be developed to control the disease. Thermocautery or photocoagulation and indenting the globe so as to bring the choroid nearer the break by scleral buckling forms the basis of modern surgery of retinal detachment. Vitreoretinal diseases, macular degeneration, diabetic retinopathy are no longer considered problematic. We are optimistic that more clinical breakthroughs are expected in the 21st century with new advances of ophthalmic researches.
