Summary
The triple procedure safely restores vision in patients with corneal disease and cataracts. However, refractive outcomes may be unpredictable, requiring careful management post-surgery.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Cataract Surgery
Background:
- Coexisting corneal pathologies and cataracts necessitate combined surgical approaches.
- The triple procedure, combining penetrating keratoplasty (PK) with cataract extraction and intraocular lens (IOL) implantation, addresses these dual conditions.
- Evaluating different cataract extraction techniques within the triple procedure is crucial for optimizing outcomes.
Purpose of the Study:
- To assess the clinical outcomes of the triple procedure (PK, cataract removal, IOL implantation).
- To compare the safety and efficacy of open-sky extracapsular cataract extraction (ECCE) versus phacoemulsification (PE) during PK.
- To analyze visual acuity, refractive results, graft clarity, and complications.
Main Methods:
- Retrospective comparative study of patients undergoing the triple procedure.
- Two cataract extraction techniques were compared: ECCE with ciliary sulcus IOL fixation and PE with capsular bag IOL fixation.
- Key outcome measures included best spectacle-corrected visual acuity (BSCVA), refractive error, graft clarity, and complications.
Main Results:
- Significant improvement in mean BSCVA from 1.40 to 0.44 LogMAR (P<0.001).
- Mean postoperative refractive error was -2.13±3.02 D, deviating significantly from the target refraction (P=0.004).
- Corneal graft clarity was maintained in 89.5% of eyes at final follow-up.
Conclusions:
- The triple procedure is a safe and effective method for visual restoration in patients with combined corneal and cataract issues.
- While visual acuity and graft clarity are favorable, postoperative refractive outcomes can be unpredictable.
- Further research may be needed to refine refractive predictability in triple procedures.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
