Scleral fixation using suture retrieval through a scleral tunnel

Area of Science:

• Ophthalmology
• Ophthalmic Surgery

Background:

• Scleral fixation of intraocular lenses (IOLs) is a crucial surgical technique.
• Traditional methods often involve scleral flaps, which can be complex to construct and close.

Purpose of the Study:

• To present a modified scleral fixation technique using a scleral tunnel for suture fixation of IOLs.
• To highlight the advantages of the scleral tunnel approach over scleral flaps.

Main Methods:

• A variation of scleral fixation using a scleral tunnel for suture placement.
• Passage of a double-armed suture through the scleral tunnel roof.
• Retrieval and tying of suture ends through an external incision.

Main Results:

• The scleral tunnel is simpler to construct and requires no suture closure compared to scleral flaps.
• The technique provides a larger surface area for suture placement via ab externo or ab interno approaches.
• Suture knots are concealed within the tunnel, eliminating the need for rotation.

Conclusions:

• Scleral fixation via a scleral tunnel offers a simplified and effective method for IOL fixation.
• This technique is advantageous for securing IOLs and other intraocular devices.
• The method streamlines the surgical process and improves outcomes.
