Clinical Causes: Surgical removal of the natural lens during cataract surgery can lead to aphakia, which may predispose the cornea to damage. Inadequate post-surgical eye care or complications can result in corneal edema and bullous formation. Chronic corneal exposure or inadequate tear film coverage can cause corneal irritation and swelling. Prolonged use of certain medications, such as topical steroids, affecting corneal health. Pre-existing corneal diseases or conditions that compromise corneal integrity. Presence of intraocular lens (IOL) or other surgical materials that may cause mechanical irritation. Infections or inflammatory responses following surgery that impair corneal tissue. Elevated intraocular pressure (glaucoma) post-surgery, stressing the corneal tissue.

Key Symptoms: Blurred or decreased vision in the affected eye. Sensitivity to light (photophobia). Eye discomfort or soreness. Feeling of pressure or heaviness in the eye. Presence of fluid-filled blisters or bullae on the corneal surface. Tearing or watery eyes. Corneal swelling leading to a hazy appearance when examined. In severe cases, open sores or erosions on the cornea.

Diagnosis Path: Slit-lamp biomicroscopy: to visually assess corneal clarity, the presence of bullae, and any structural abnormalities. Corneal pachymetry: to measure corneal thickness and detect edema. Fluorescein staining: to identify epithelial erosions or ulcerations. Intraocular pressure measurement: to rule out or manage glaucoma components. Additional imaging tests or laboratory investigations if infection or inflammatory causes are suspected.

Treatment Protocols: Artificial tears and lubricating eye drops to promote comfort and protect the cornea. Hypertonic saline solutions to reduce corneal edema by drawing fluid out of the cornea. Topical antibiotics or anti-inflammatory medications to treat secondary infections or inflammation. Bandage contact lenses to protect the cornea and reduce pain. Surgical options such as cautery or conjunctival flaps in severe cases of bullae formation. Corneal transplantation procedures like keratoplasty for advanced or unresponsive cases. Addressing underlying causes such as intraocular pressure management or post-surgical complications. Regular follow-up to monitor healing and prevent recurrence.
