Cataract: Diagnosis & Treatment

Overview

A cataract is an eye disease characterized by clouding of the lens, leading to blurred vision and, if left untreated, potential vision loss. Lens opacity can be caused by natural aging, inflammatory processes, trauma, or other underlying conditions.

Types of Cataracts

• Anterior Subcapsular Cataract – Clouding in the front portion of the lens

• Nuclear Sclerotic Cataract – Hardening and yellowing of the central lens nucleus

• Posterior Subcapsular Cataract – Opacity at the back of the lens, often affecting near vision

Diagnosis

A comprehensive eye examination is required to confirm the presence and severity of a cataract. Diagnostic methods include:

• Biomicroscopy using a slit lamp – To assess the location and density of lens clouding

• Measurement of visual acuity – To evaluate the impact of the cataract on vision

• Fundus examination – To check for retinal abnormalities

• Measurement of intraocular pressure (IOP) – To rule out coexisting conditions like glaucoma

Treatment Options

Surgical Treatment:

• The only effective treatment for cataracts is surgical removal of the cloudy lens, followed by the implantation of an intraocular lens (IOL) to restore clear vision.

Cost of Diagnosis & Treatment:

• 3,200,000 – 6,000,000 KRW
