MICRO INCISION VITRECTOMY SYSTEM (M.I.V.S.) AT RETINA INSTITUTE OF KARNATAKA.

WHAT IS M.I.V.S.?

Vitrectomy as we know involves making holes (about 1.15mm diameter) in the white part of our eye -the sclera to gain access into the vitreous cavity and the
retina. Conventionally stitches are placed at the end of surgery to close these holes which heal over a few weeks.

In micro incision vitrectomy the size of the hole is much smaller, that is less than 0.72mm in diameter and is made with specialized instruments therefore
they are self sealing i.e. they close by themselves without the need for stitches.

HOW IS MICROINCISION

VITRECTOMY PERFORMED?

Micro incision vitrectomy is done with a specialized vitrectomy system called CONSTELLATION.

• CONSTELLATION is world’s number one in micro incision vitrectomy.
• In less than a year from its introduction CONSTELLATION has become the gold standard machine for vitrectomy worldwide.
• R.I.K is one of the very few hospitals in India providing this high end service to the patients.

WHAT ARE THE ADVANTAGES OF MICROINCISION VITRECTOMY?

It has significant advantages over conventional vitrectomy systems like,

• The surgeon can perform complex retinal surgeries through very small holes in the sclera.
• High speed ULTRAVIT probe which can operate at 5000 cuts per minute more than twice the conventional vitrectomy probe, means faster and finer
  surgery.
• High precision instruments give perfect control for surgeon that increases the precision and safety of surgery significantly.
• Bright XENON ILLUMINATION to view the smallest defects in the retina and treat them.
• Integrated PUREPOINT laser - laser treatment can be done during surgery itself.
• 23 gauge and 25 gauge vitrectomy-No stitches at the end of the surgery so no discomfort.
• Since there are no sutures, post-operative patient comfort is better.
• Postoperative pain is less.
• The foreign –body sensation in the operated eye due to the sutures does not occur.
• The eye heals faster.
• Cosmetically better: postoperative redness is absent or minimal. External appearance of the eye comes back to normal within a week. Comparison of external appearance of the eye between a conventional and MICROINCISION vitrectomy. Conventional vitrectomy Micro incision vitrectomy

WHAT ARE THE RETINAL DISEASES FOR WHICH MICROINCISION VITRECTOMY CAN BE DONE?

• Vitreous hemorrhage
• Epiretinal Membrane
• Vitreo-macular traction
• Macular hole.
• Proliferative diabetic retinopathy with hemorrhage
• Some cases of Retinal detachment

WHAT ARE THE LIMITATIONS OF MICROINCISION VITRECTOMY?

Micro incision vitrectomy is not done in all types vitrectomies for retinal diseases. In retinal diseases requiring scleral buckling with vitrectomy or in eyes with
advanced retinal disease where extensive membrane surgery is required a micro incision vitrectomy is not suitable.

Whenever you are advised vitrectomy by your retina specialist at RIK you can discuss with him and opt for the MICROINCISION VITRECTOMY SYSTEM ( M.I.V.S.) Patient information literature/MIVS/10-08-2010/RIK/SYN.
