Microincision cataract surgery
Also written as: MICS — Microincision cataract surgery
Cataract surgical technique using incisions smaller than 2.2mm to reduce induced astigmatism and promote faster healing.
Full Definition
Microincision cataract surgery (MICS) represents an advanced phacoemulsification technique utilizing incisions smaller than 2.2mm, typically 1.8-2.0mm, to minimize surgical trauma and optimize visual outcomes. The technique requires specialized instrumentation including smaller phacoemulsification tips, reduced-diameter irrigation/aspiration systems, and foldable IOLs compatible with smaller incisions. MICS offers theoretical advantages including reduced surgically induced astigmatism, faster wound healing, improved wound stability, and decreased risk of endophthalmitis. However, the smaller incision may limit surgical maneuverability and require modified techniques for complex cases. Success depends on proper case selection, surgeon experience, and appropriate technology platforms designed for microincision surgery.
Usage
Usage note: Incision size should be specified (typically 1.8-2.0mm) to distinguish from conventional small-incision techniques (2.2-3.0mm).
In Context
- "Microincision cataract surgery was selected to minimize astigmatic change in this patient with pre-existing corneal irregularity." — Surgical planning
- "The 1.8mm incision used in MICS required no sutures and demonstrated excellent wound integrity postoperatively." — Technique description
