Most glaucoma patients with cataracts require surgery. Most of these patients have short eye axes, early onset of “phakic” symptoms, crowded anterior segment, and cataracts in the expansion phase. Cataract surgery alone, glaucoma surgery and then cataract surgery after a period of time. Combined glaucoma cataract surgery. The decision to operate is based on the type and severity of glaucoma, the maturity of the cataract, and the individualized assessment of the patient’s health status. ”Early open-angle glaucoma with topical ophthalmic pressure control and early closed-angle glaucoma with a mostly open atrial angle can be treated with cataract surgery alone. If glaucoma surgery is performed first and then cataract surgery is performed, the trauma to the eye may be aggravated by the two operations before and after, and the effect of the original glaucoma surgery in lowering IOP may be reduced or lost by cataract surgery. For patients with glaucoma requiring surgery and significant cataract, combined glaucoma cataract surgery is often used. This surgical approach allows patients to recover their vision more quickly, and postoperative IOP can be effectively controlled, avoiding the need for reoperation and reducing the emotional and financial burden for patients. With the development of ultrasound emulsification technology, combined glaucoma-cataract surgery is becoming more and more effective and has become the preferred treatment option for this type of patients.
