700 micron Cataract Surgery • The smallest incision size for lens surgery until present time
It gives to the surgeon the ability to work in a closed enviroment • This advantage is a true value in cases of posterior capsule rupture. Notice the posterior tear in this picture; notice the closed enviroment.
Surgical Technique • Do not stop irrigation, just decrease the infusion force. • Withdraw from the eye the phaco tip with positive intraocular pressure.
Surgical Technique • Insert viscoelastic material with your non-dominating hand. • Stop irrigation and retire the infusion until the anterior chamber is completely distended.
Surgical Technique • Explore the anterior chamber through both incisions.. • Look for vitreous strands and the anterior and posterior capsule remanents.
Surgical Technique • Perform high speed anterior vitrectomy in a biaxial mode. • Use the same irrigating cannula with a posterior mode vitrector.
Surgical Technique • Cut as much vitreous body as you might need. • Take care for the anterior capsule remanent. • Go behind the iris as you might need; you are working in a complete closed enviroment.
Surgical Technique • Retire the vitrector without stop irrigation. • Switch with your non-dominant hand for visco. • Stop irrigation and retire the irrigating cannula until the chamber has been formed with visco.
Results • In 700 cataract surgeries performed by one surgeon with 700 micron tech. 15 cases were complicated with posterior capsule rupture. • In all cases the management of the vitreous was made with the same 700 micron technology in a biaxial approach; the technique as was described here.
Results • Mean surgical time for anterior vitrectomy was 1.12 mins. No surge or collapses were present. Mean BSS consumption was of 29 cc. Complete visual recovery was present at 4 weeks. No other complications were noticed in one year follow-up.
Conclusions • 700-micron approach for a biaxial anterior vitrectomy in cases of vitreous loss during cataract surgery is an effective and safe technique with no short-term complications. Thank you very much
