Abstract Details

Purpose:

To evaluate IOL implantation through the transconjunctival scleral corneal single plane incision with bimanual phacoemulsification

Setting:

Transconjunctival scleral corneal single-plane incision cataract surgery has several advantages, including coverage of the scleral corneal incision with preserved conjunctiva. However, associated risks include intraoperative chemosis and postoperative incision exposure. In the present study we combined scleral corneal one-plane incision cataract surgery with bimanual phacoemulsification.

Methods:

Methods (100 words) Forty bimanual phacoemulsification cataract operations were performed through 1.4-mm incisions. After extraction of the crystalline lens, scleral corneal single-plane incisions were made through conjunctiva and intraocular lenses were implanted through them.The scleral corneal one-plane incisions were randomly chosen to be either 2.0 or 2.4 mm long. The condition of the scleral corneal incisions was evaluated 1 day, 1 week, and 1 month after surgery. Surgically induced corneal astigmatism was evaluated with the Jaffe method, and intraoperative and postoperative complications of implantation were assessed.

Results:

Regardless of their length, all incisions were closed postoperatively without leakage. There was also no intraoperative conjunctiva chemosis, postoperative incision exposure, or intraoperative or postoperative complications in any patient. The mean corneal astigmatism 1 week after surgery did not differ significantly between patients with 2.0-mm incisions (0.41 ± 0.27 D) and those with 2.4-mm incision (0.53 ± 0.27 D).

Conclusions:

By means of IOL implantation through the transconjunctival scleral corneal single plane incision with bimanual phacoemulsification, incisions were covered with preserved conjunctiva without intraoperative chemosis or postoperative incision exposure. This technique combines the advantages of clear corneal incisions and sclerocorneal incisions. Intraocular lenses were safely inserted through 2.0-mm transconjunctival scleral corneal single-plane incisions. FINANCIAL DISCLOSURE?: No
