Purpose:
To describe a modified technique for performing sutureless sclerotomies for pars plana vitrectomy and to examine its efficacy and safety.
Design:
Retrospective, interventional case series.
Methods:
Self-sealing sclerotomies were created in 35 consecutive cases by oblique penetration of the sclera with a 19G MVR blade.
Results:
All but two (2.9%) of the sclerotomies were watertight without suturing at the end of surgery. A conjunctival bleb was observed during the first postoperative week in one case, but it resolved without intervention.
Conclusions:
Construction of sutureless sclerotomies by this technique is simpler and more rapid compared with previously described techniques. The resulting sclerotomies are more resistant to stretching and tearing of the tunnel's roof, they rarely need suturing, and insertion of instruments is facilitated.
Insights
This study introduces a new, simpler method for creating sutureless sclerotomies during pars plana vitrectomy. The technique proved effective and safe, with most incisions remaining watertight without sutures.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Pars plana vitrectomy is a common ophthalmic surgical procedure.
- Sclerotomies are essential entry points for surgical instruments during vitrectomy.
- Traditional methods often require suturing, adding time and complexity.
Purpose of the Study:
- To present a modified technique for sutureless sclerotomies.
- To evaluate the efficacy and safety of this novel approach for pars plana vitrectomy.
Main Methods:
- A retrospective, interventional case series design was employed.
- Self-sealing sclerotomies were created using oblique scleral penetration with a 19G MVR blade.
- The technique was applied in 35 consecutive cases.
Main Results:
- Sclerotomies were watertight without suturing in 97.1% of cases.
- A single case of a conjunctival bleb was observed postoperatively, resolving spontaneously.
- The technique demonstrated high efficacy in creating secure entry points.
Conclusions:
- The modified technique offers a simpler and faster method for sutureless sclerotomies.
- Sclerotomies created are more resistant to tearing and facilitate instrument insertion.
- This approach enhances the efficiency and safety of pars plana vitrectomy.
