AI Article Synopsis
- This study aimed to analyze the occurrence of secondary pigment dispersion syndrome (PDS) and pigmentary glaucoma following sulcus transscleral fixation of a specific type of intraocular lens (IOL) in aphakic patients in China.
- A retrospective review of 23 eyes from 21 patients revealed that 17 eyes experienced PDS and 7 had pigmentary glaucoma, with notable postoperative complications including high pigment deposits and instances of reverse pupillary block.
- The findings concluded that the specific IOL used was unsuitable for this surgical technique due to the significant risk of developing PDS and pigmentary glaucoma in the studied population.
Article Abstract
Purpose: To describe secondary pigment dispersion syndrome (PDS) and pigmentary glaucoma after secondary sulcus transscleral fixation of 1-piece hydrophobic acrylic foldable posterior chamber intraocular lenses (PC IOLs) in aphakic patients in a Chinese population.
Setting: Department of Ophthalmology, Qingdao Municipal Hospital, Qingdao, China.
Design: Retrospective case series.
Methods: This chart review included eyes that had secondary sulcus transscleral fixation of a 1-piece hydrophobic acrylic foldable PC IOL (Tecnis ZCB00) between March 2011 and March 2014. The patients' demographic data, clinical data, postoperative complications, intervals between initial surgery and the onset of PDS, pigmentary glaucoma occurrences, and findings on slitlamp biomicroscopy, gonioscopy, and ultrasound biomicroscopy (UBM) were recorded.
Results: The study comprised 23 consecutive eyes of 21 patients. Seventeen eyes of 16 patients were diagnosed with PDS, and 7 eyes of 6 patients were diagnosed with pigmentary glaucoma. The slitlamp examination and UBM showed that the location between the IOL optic and the posterior surface of the iris was very close. Slitlamp examination of the anterior chamber angle using a gonioscope showed dense pigment deposition on the IOL surfaces. A reverse pupillary block was found in 10 eyes of 9 patients. Other postoperative complications included intraocular hemorrhage, pupillary capture of the IOL optic, IOL tilt, IOL decentration, IOL dislocation, and suture erosion.
Conclusion: The 1-piece hydrophobic acrylic foldable PC IOL was not suitable for sulcus transscleral fixation because of a high incidence of PDS and pigmentary glaucoma after surgery in a Chinese population.

Introduction: The aims of lens removal surgery are to re-establish or preserve both a clear visual axis and emmetropic vision. Trans-scleral intraocular lens (IOL) fixation has been described in cases where lens capsule instability precludes the insertion of a prosthetic intraocular lens into the lens capsule. Previous techniques have necessitated enlargement of the corneal incision to accommodate either a rigid polymethylmethacrylate IOL or an acrylic foldable IOL inserted using forceps.

Purpose: This retrospective study introduces and evaluates transscleral fixation using a horizontal mattress suture of a conventional injectable acrylic intraocular lens (IOL) inserted through a 3-mm corneal incision in dogs.
Materials And Methods: This technique was applied to four groups: lens subluxation (group SL, n = 15), anterior or posterior lens luxation (group APLL, n = 9), lens capsule tear or rupture (group LCTR, n = 7), and dislocation of the lens capsule containing an IOL (group IOLD, n = 4).
Results: Patients were followed up for an average of 366.
Purpose: To present an electrocoagulation fixation technique for one-piece intraocular lens (IOL) scleral flapless fixation with sutures without knots.
Methods: First of all, after repeated tests and comparisons, we chose 8-0 polypropylene suture as the material for electrocoagulation fixation of one-piece IOL haptics because of its proper elasticity and size. A transscleral tunnel puncture at the pars plana was performed using an arc-shaped needle with 8-0 polypropylene suture.

Purpose: To report a novel approach for removal of intraocular foreign body in the ciliary sulcus.
Observations: A 72-year-old male presented with an intraocular foreign body embedded in the ciliary body, localized with ultrasound biomicroscopy. An intraoperative endoscopic camera was then used to directly visualize the foreign body in the ciliary body and the object was successfully removed with intraocular forceps.
