Abstract
In cases where there is a lack of capsular support, intraocular
lenses (IOLs) can be implanted in the anterior chamber and fixed to the
iris or in the posterior chamber and fixed to the sclera, typically with a
trans-scleral suture.
Modern flexible open-loop anterior chamber intraocular lenses
(IOLs) have a generally positive track record. However, there are still
concerns regarding secondary glaucoma and loss of endothelial cells.
These concerns are particularly significant in eyes that may have been
exposed to trauma or complicated surgery, where the endothelium or
anterior chamber angle may be compromised.
Reports said that in patients with early endothelial cell loss and
corneal decompensation, lens replacement with a posterior chamber
intraocular lens (PC IOL) can prevent progression to bullous
keratopathy.
Scleral fixation intraocular lenses (IOL) are a good alternative,
especially in cases of iris atrophy, traumatic mydriasis, or corneal
endothelial problems. Compared to other types of IOLs, the relatively
normal anatomical implantation site of scleral fixation IOLs results in
fewer complications due to their placement away from the angle and
corneal endothelium.
Despite these advantages, suture-related complications such as
suture exposure, rupture or erosion may occur, which can cause
endophthalmitis or IOL instability respectively, so many
ophthalmologists tried multiple techniques for implantation of stable SF
IOL without the need for sutures.
This work aims to evaluate the flanged sutureless intra-scleral
haptic fixation technique for secondary IOL implantation regarding
procedure difficulty, IOL centration and stability, intraoperative and
postoperative complications and visual outcomes.
The study included 22 patients with aphakia and absence of
capsular support. It was conducted in the ophthalmology department of
Menoufia University Hospital from April 2022 to April 2023 after
receiving approval from the hospital’s ethical committee.
