Patients with low intraocular pressure (IOP) who cannot undergo cataract surgery need to find out the cause of the IOP and follow the doctor’s instructions to control the IOP through medication and surgery before considering cataract surgery. Because cataract is an elective surgery, if the patient’s intraocular pressure is low and not suitable for cataract surgery, the patient can control the intraocular pressure first, and then perform cataract surgery. If cataract surgery is performed in a low intraocular pressure state, the patient is at a higher risk of surgical complications. Wound leakage, choroidal detachment and other factors can lead to lower IOP. Patients can use atropine gel and wound closure as prescribed by the doctor to stabilize IOP before considering cataract surgery. If the patient’s intraocular pressure is persistently low, the patient may experience atrophy of the eyeball. It is recommended that patients with low IOP seek prompt medical attention to assess their condition and follow medical advice.
