Mr Nicholas Glover  - Consultant Cataract Surgeon
Refractive Surgery
Standard catarct surgery lens implants will correct patients with long or short sight but may not fully treat patients with significant astigmatism. They will still require spectacle correction at both near and distance
Astigmatism is an optical defect in which vision is blurred due to an irregular curvature of the cornea or lens. The two types of astigmatism are regular and irregular. 
    • Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens, and cannot be corrected by standard spectacle lenses.

    • Regular astigmatism arising from either the cornea or crystalline lens can be corrected by eyeglasses or toric lenses.
Although mild astigmatism may be asymptomatic, higher degrees of astigmatism may cause symptoms such as blurry vision, squinting, fatigue, or headaches. 

A 'toric' surface resembles a section of the surface of a Rugby ball. This optical shape gives rise to astigmatism in the eye

The use of a Toric lens implant can correct this, but they are more expensive than a standard lens so will increase the price of surgery. We will discuss at your appointment if this lens would benefit you.
