Summary
Microincisional vitrectomy surgery (MIVS) can lead to wound leaks, causing complications. A new suturing technique during cannula withdrawal effectively seals MIVS ports, improving intraocular pressure control.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Microincisional vitrectomy surgery (MIVS) offers advantages but is prone to wound leaks.
- Wound leaks can cause hypotony, choroidal detachment, and endophthalmitis.
- Existing methods for wound closure in MIVS have limitations in preventing leaks.
Purpose of the Study:
- To present a novel technique for suturing MIVS ports during cannula withdrawal.
- To address challenges in port identification and suturing, especially in cases prone to leakage.
Main Methods:
- A new suturing technique was developed, initiating port closure as the cannula is withdrawn.
- The technique was applied in 30 consecutive MIVS cases.
- Postoperative intraocular pressure was measured on day one.
Main Results:
- The technique facilitated proper port identification and suturing.
- Mean postoperative intraocular pressure on day one was 18.82 ± 12.24 mmHg.
- The method proved effective, particularly for anticipated leaks.
Conclusions:
- This technique effectively seals MIVS ports, reducing the risk of wound leaks.
- It simplifies port suturing, even in challenging cases.
- The method contributes to better intraocular pressure management after MIVS.
