It began with small-incision cataract surgery with an incision less than 4mm in size, as against a 12-14 mm incision in conventional cataract surgery (called extracapsular cataract extraction). The introduction of phacoemulsification changed cataract surgery forever, heralding the onset of sophisticated mechanization. The most significant advancement in this regard are, one, a decrease in the size of the incision, and two, the use of premium IOLs. The latest in the former is the development of the surgical technique, Microincision Cataract Surgery (MICS); where incision size is less than 2mm in size.
In case you have cataracts, your doctor will try and improve your vision using glasses. In case, if it does not get better with the glasses, or you struggle with glare, he or she will suggest that you to consider cataract surgery. Most doctors find that patient satisfaction and visual recovery are both the best after MICS, and they will be happy to discuss its risks and benefits with you.
MICS was first described by Jorge Alió in 2002, who defined the technique that relied on principles of bimanuality, new tools, fluidics and a smaller incision. Conventional phacoemulsification uses a larger incision as compared to MICS, as is evident from the terminology itself. In MICS, the incision size is lower than 2.0 mm and ranges from 1.5 to 1.8 mm depending on surgeon preference. The machine used for MICS is more sophisticated. The bimanual irrigation and aspiration handpiece ensure that less ultrasound or phaco energy is used during each surgery. The smaller incision size, as well as the use of less energy, makes this surgery safer and helps in faster healing.
