Where is the incision in cataract surgery?

During a procedure called phacoemulsification (fak-o-e-mul-sih-fih-KAY-shun), your surgeon makes a tiny incision in the front of your eye (cornea) and inserts a needle-thin probe into the lens substance where the cataract has formed.

How is the incision closed after cataract surgery?

Stromal hydration is one of the most frequently used methods to seal sutureless corneal incisions. The literature is divided over the effectiveness of stromal hydration. One study of 80 patients found that stromal hydration was effective. Another study reported a 66.7% leak rate with stromally hydrated incisions.

How is the incision made in cataract surgery?

Phacoemulsification, or phaco. A small incision is made on the side of the cornea, the clear, dome-shaped surface that covers the front of the eye. Your doctor inserts a tiny probe into the eye. This device emits ultrasound waves that soften and break up the lens so that it can be removed by suction.

What comes out when you make an incision in the cornea?

If you make a cut in the cornea, a clear fluid oozes out. That’s the aqueous humor, which is made of protein and water. The aqueous humor helps give the eye its shape. A tough, clear covering over the iris and the pupil that helps protect the eye.

What is the purpose of the scleral tunnel incision?

Scleral tunnel incision trabeculectomy was developed to minimize early postoperative hypotony and complications related to excessive filtration. The present study was conducted to evaluate whether the new modified technique can reduce the risk of overfiltration and improve the rate of success of trabeculectomy.

Why is incision construction important in cataract surgery?

Cataract incision construction is of utmost importance in phacoemulsification cataract surgery. The initial wound construction influences the fluidic balance of the anterior segment, lays the foundation for all additional steps of the surgery, and plays an important role in the immediate post-operative period when the wound is most unstable.

How is the flap of the scleral dissected?

The scleral flap was dissected beginning with a 4 mm wide groove 2–3 mm from the limbus with a 30° knife and the flap was thereafter dissected with a crescent‐shaped microblade. The sides of the flap were opened only half‐way to the limbus.

Where is the releasable suture on the scleral flap?

The scleral flap was sutured with one 10–0 nylon releasable “slipknot” suture on the middle of the flap and the loose end passed inside the corneal tissue on the cornea ( Figs. 1–3 ). The releasable suture was placed using the technique described by Cohen and Osher ( Cohen & Osher 1988) and modified by Kolker ( Kolker et al. 1993 ).
