Cataract Surgery

 

Post-operative Infection after Cataract Surgery

A cataract is a cloudiness of the normally clear lens in the eye. Cataract is common among the elderly and over 80% of people aged 60 years old and above have vision impairment from a cataract in Singapore. As we age, some of the proteins in the lens of our eye may clump together and start to cloud the lens. Cataract is often a progressive age-related condition. Cataract can reduce the sharpness of the image reaching the retina, add a brownish tint to one’s vision or cause glare.

Cataract is detected through a comprehensive eye examination, including a visual acuity test and dilated eye exam. The only effective treatment for cataract is surgery. The primary indication for surgery is when the patient’s reduced vision affects his/her ability to perform daily activities (e.g., driving or reading). Cataract surgery involves the removal of the clouded lens and replacing it with a lens implant. Although cataract surgery is generally safe, it carries the risk of bleeding and infection as with other types of surgical procedures.

Endophthalmitis is a vision threatening infection of the eye that can occur after cataract surgery. Hence, it is crucial that the doctor takes precautions to reduce the chances of this infection occurring. From January 2016 to June 2018, there were no cases of endophthalmitis in our patients who had undergone cataract surgery.
