There are two main types of ophthalmic surgical systems available in the market that include laser ophthalmic surgical systems and phacoemulsification ophthalmic surgical systems. The laser ophthalmic surgical systems are used for a number of ophthalmic surgeries including, glaucoma surgery, diabetic retinopathy, and refractive surgery. The Laser ophthalmic surgical systems can be broadly classified into three types that are photocoagulating lasers, photodisrupting lasers, and photoablating lasers. In general for photocoagulation of abnormal vascular tissue in the retina ophthalmologists use argon, krypton, dye, diode and Nd:YAG lasers. For photodynamic treatment of intraocular tumors Dye and diode lasers are generally used. Nd:YAG ophthalmic lasers are also commonly used for microsurgery in the anterior portions of the eye. For cataract surgery, phacoemulsification ophthalmic surgical systems are used. This system emulsifies the lens using ultrasound prior to its removal by suction. The phacoemulsification ophthalmic surgical systems can also be used for anterior vitrectomy.
