Uveitis patients have vision that is between one and two lines worse than those without the condition following cataract surgery, new research has found.
A study published in the British Journal of Ophthalmology found that although most patients had sharper vision following cataract surgery, the average post-operation acuity for patients with uveitis was worse than those without the condition.
Researchers studied medical record data for patients undergoing cataract extraction from eight independent clinical sites in the UK between 2010 and 2014.
A group of 1173 eyes with a recorded diagnosis of uveitis were compared with a reference group of 95,573 eyes without the inflammatory eye condition.
The study found that patients with uveitis had worse preoperative visual acuity (0.87 vs 0.65 logarithm of the minimum angle of resolution units), had shorter axial lengths and a higher incidence of ocular co-pathology including glaucoma.
More uveitis patients had documented small pupils, required additional surgical procedures and developed intraoperative complications than in the reference group.
Researchers emphasised that the study highlighted the complex surgical demands of uveitis and would allow more accurate preoperative counselling and planning.
