Intraocular pressure after cataract surgery with Healon
Summary
Irrigating sodium hyaluronate (Healon) after cataract surgery significantly reduces the risk of increased intraocular pressure (IOP). Unirrigated Healon led to higher IOP spikes in 35% of patients compared to 11% in irrigated patients.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Biomaterials in Medicine
Background:
- Cataract extraction with posterior chamber lens implantation is a common procedure.
- Sodium hyaluronate (Healon) is frequently used during such surgeries.
- Elevated intraocular pressure (IOP) is a potential post-operative complication.
Purpose of the Study:
- To investigate the effect of Healon on post-operative intraocular pressure (IOP).
- To compare IOP outcomes between Healon retention and Healon irrigation groups.
Main Methods:
- A comparative study involving 75 patients undergoing extracapsular cataract extraction and posterior chamber lens implantation.
- Sodium hyaluronate (Healon) was used in all cases.
- Patients were divided into two groups: Healon left in the anterior chamber (n=40) and Healon irrigated out (n=35).
Main Results:
- A significantly higher percentage of patients (35%) experienced an IOP increase ≥ 20 mm Hg in the Healon retention group within 10 hours post-surgery.
- Only 11% of patients in the Healon irrigation group showed a similar IOP increase.
- At 20 hours post-surgery, the average IOP was markedly lower in the irrigated group (15.6 mm Hg) compared to the non-irrigated group (23.8 mm Hg).
Conclusions:
- Leaving Healon in the anterior chamber after cataract surgery is associated with a higher incidence of post-operative IOP elevation.
- Irrigating Healon from the anterior chamber appears to be a safer approach, mitigating the risk of significant IOP spikes.
- This finding suggests a modification in surgical technique to improve patient outcomes and reduce complications.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
