Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure. This procedure minimises the incision size and reduces the recovery time and risk of surgery-induced astigmatism.
Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.
Aphakia is the absence of the lens of the eye, due to surgical removal, such as in cataract surgery, a perforating wound or ulcer, or congenital anomaly. It causes a loss of ability to maintain focus (accommodation), high degree of farsightedness (hyperopia), and a deep anterior chamber. Complications include detachment of the vitreous or retina, and glaucoma.
Astigmatism is a type of refractive error due to rotational asymmetry in the eye's refractive power. This results in distorted or blurred vision at any distance. Other symptoms can include eyestrain, headaches, and trouble driving at night. Astigmatism often occurs at birth and can change or develop later in life. If it occurs in early life and is left untreated, it may result in amblyopia.
Iridodialysis is a localized separation or tearing away of the iris from its attachment to the ciliary body.
Jeffery J. Machat MD, FRCSC, DABO is an ophthalmologist in the United States and Canada specializing in surgical vision correction better known as refractive eye surgery. He is most known for being the Co-Founder of TLC Laser Eye Centers with Elias Vamvakas in 1993. The first TLC clinic was located in Windsor, Canada and treated thousands of patients from across all of North America. The clinic also hosted thousands of eye care specialists trying to learn about LASIK and PRK prior to US FDA approval which came three years later. Together Vamvakas and Machat built an incredible company of 83 LASIK clinics through both organic growth and strategic acquisition by May 2002 to become the largest provider of LASIK in North America. Dr. Machat pioneered not only LASIK but the concept of Optometric Comanagement throughout the 1990s, helping build a TLC network of over 14,000 referring optometrists by 2000. In 2005-2006, Machat spent time in Europe working to build Optical Express, helping David Moulsdale, owner and Founder, to transform the company from 300 optical stores into the leading provider of LASIK vision correction in Europe with 55 clinics in the span of 2 years.
The Alpins Method is a system to plan and analyze the results of refractive surgical procedures, such as laser in-situ keratomileus (LASIK). The Alpins Method is also used to plan cataract/toric intraocular lens (IOL) surgical procedures.
Noshir Minoo Shroff is an Indian ophthalmologist notable for pioneering intraocular lens implantation surgery in India. He was awarded the Padma Bhushan in 2010 by the Indian government for his services to medicine.
Jeewan Singh Titiyal is an Indian ophthalmologist, credited with the first live cornea transplant surgery by an Indian doctor. He was honoured by the Government of India, in 2014, by bestowing on him the Padma Shri, the fourth highest civilian award, for his services to the field of medicine.
Harsh Kumar is ophthalmologist, who is reported to have described nine laser surgical procedures for glaucoma and anterior segment of which one procedure is cited by Shields Text Book of Glaucoma, a known reference book on glaucoma management. He is the director of Glaucoma Services at Centre for Sight, New Delhi and also serves at the Indraprastha Apollo Hospitals, Delhi. He was honoured by the Government of India in 2015 with Padma Shri, the fourth highest Indian civilian award.
Dr Amar Agarwal M.S., FRCS, F.R.C.Ophth is an Indian ophthalmologist and chairman and managing director of Dr. Agarwal's Eye Hospital and Eye Research Centre in India, which includes 190 + eye hospitals. He is the recipient of the Best Doctor award of the State government from then Chief Minister of Tamil Nadu J Jayalalithaa on 15 August 2014. He is also the past President of the International Society of Refractive Surgery (ISRS) and Secretary General of the Intraocular Implant and Refractive Society of India (IIRSI).
Intraocular lens scaffold, or IOL scaffold technique, is a surgical procedure in ophthalmology. In cases where the posterior lens capsule is ruptured and the cataract is present, an intraocular lens (IOL) can be inserted under the cataract. The IOL acts as a scaffold, and prevents the cataract pieces from falling to the back of the eye. The cataract can then be safely removed by emulsifying it with ultrasound and aspiration. This technique is called IOL scaffold, and was initiated by Amar Agarwal at Dr. Agarwal's Eye Hospital in Chennai, India.
Micro-invasive glaucoma surgery (MIGS) is the latest advance in surgical treatment for glaucoma, which aims to reduce intraocular pressure by either increasing outflow of aqueous humor or reducing its production. MIGS comprises a group of surgical procedures which share common features. MIGS procedures involve a minimally invasive approach, often with small cuts or micro-incisions through the cornea that causes the least amount of trauma to surrounding scleral and conjunctival tissues. The techniques minimize tissue scarring, allowing for the possibility of traditional glaucoma procedures such as trabeculectomy or glaucoma valve implantation to be performed in the future if needed.
Mahipal S. Sachdev is an Indian ophthalmologist and the Chairman of Centre for Sight, a chain of Eye Hospitals in India. He is known as one of the pioneers of the phacoemulsification procedure in India. He is the co-author of A Practical Guide to Phacoemulsification, the first Indian book on the topic. The Government of India awarded him the fourth highest civilian honour of the Padma Shri, in 2007, for his contributions to Indian medicine. He is the Chairman Scientific Committee of the Intraocular Implant and Refractive Society of India, IIRSI.

He is the Chief Surgical and Medical Director at Mehta International Eye Institute, a Mumbai-based specialty eye hospital founded by him.

Robert M. Schertzer is a Canadian ophthalmologist with a subspecialty in glaucoma treatment. He currently serves as the Clinical Associate Professor of Ophthalmology and Visual Sciences at the University of British Columbia.
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing. The wound is relatively smaller than that in ECCE but is still markedly larger than a phacoemulsification wound. Comparative trials of MSICS against phaco in dense cataracts have found no statistically significant difference in outcomes but MSICS had shorter operating times and significantly lower costs. MSICS has become the method of choice in the developing world because it provides high-quality outcomes with less surgically induced astigmatism than ECCE, no suture-related problems, quick rehabilitation, and fewer post-operative visits. MSICS is easy and fast to learn for the surgeon, cost effective, simple, and applicable to almost all types of cataract.
