Phacoemulsification in Patients With Corneal Opacities

Phacoemulsification in Patients With Corneal Opacities Using Slit Illumination of the Surgical Microscope

In this retrospective case series, the feasibility of performing phacoemulsification using slit illumination in eyes with corneal opacity was assessed.

Corneal opacity is often encountered in patients seeking senile cataract surgery in developing countries. Corneal opacity impairs the intraoperative visualization during cataract surgery which increases the risk of copmlications.

Several techniques were described to enhance the intraoperative visualization such as the use of anterior endoscopy, chandeiler retroillumination, and anterior chamber endoillumination. All these techniques require costly instrumentation.

the aim of this study was to assess the feasibility of performing phacoemulsification using slit illumination of the surgical microscope without the need of additional instruments, and report the visual outcome.

Inclusion criteria:

• The presence of visually significant senile cataract.
• A recent history of progressive diminution of vision within few months.
• Stable density and size of a preexisting trachomatous corneal opacity that does not impair the pupil or lens visualization after pupillary dilatation.

Exclusion Criteria:

• History of trauma, infectious corneal ulcers, or intraocular surgery.
• Coexisting ocular diseases e.g. glaucoma, retinal detachment, and vitreous hemorrhage.
