Summary

Cataract surgery by phacoemulsification is the most commonly performed procedure in Pakistan. Cataract surgery aims for visual rehabilitation and freedom from all kinds of eyewear. Pre-operative corneal astigmatism greater than 1.0 Diopter is reported in 42% preoperatively and 58%postoperatively after implanting a monofocal intraocular lens(IOL). Visual acuity tended to worsen postoperatively with increased astigmatism4. Different treatment modalities are used to reduce astigmatism, like toric IOL. Limbal relaxing incision, actuate keratotomy, intrastromal rings, Lasik and femtosecond laser. Most of these modalities are expensive, so they cannot be afforded by the patients as Pakistan is a low-income country with a per capita income of US$1,562 (160th worldwide)

Conditions
