Glaucoma and intraocular lens implantation.

Area of Science:

• Ophthalmology
• Glaucoma Research
• Cataract Surgery

Background:

• Glaucoma patients often have coexisting cataracts, requiring careful surgical consideration.
• Extracapsular cataract extraction with posterior chamber intraocular lens implantation is a standard procedure for cataract removal.

Purpose of the Study:

• To evaluate the efficacy and safety of extracapsular cataract extraction with posterior chamber intraocular lens implantation in glaucoma patients.
• To assess visual acuity, intraocular pressure control, and disease progression post-surgery.

Main Methods:

• The study included four groups of glaucoma patients: chronic open-angle glaucoma, angle-closure glaucoma, and those previously treated with argon laser trabeculoplasty or filtering procedures.
• All patients underwent extracapsular cataract extraction with posterior chamber intraocular lens implantation.

Main Results:

• Visual acuity improved to 20/40 or better in 86% of patients.
• Intraocular pressure remained controlled, with 90% requiring equal or less medication post-surgery.
• No significant progression in optic nerve cupping or visual field loss was observed.

Conclusions:

• Extracapsular cataract extraction with posterior chamber intraocular lens implantation is a safe and effective surgical option for glaucoma patients with cataracts.
• The procedure offers significant visual rehabilitation while maintaining adequate intraocular pressure control and preventing disease progression.
