Case study: Capsular bag distension syndrome

History

JH, a 69-year-old Caucasian female and patient of long-standing, presented with the chief complaint of decreased acuity in the left eye. JH has been a patient with us since 2007 and initially presented with a refraction as follows:

R: +2.00/-0.25 x 180 (6/6)

L: +2.25/-0.75 x 177 (6/6)

Add +2.50 (N5)

In 2008, she underwent bilateral clear lens extraction which left her with a residual refraction as follows:

R: +0.75 (6/6)

L: +0.50/-1.00 x 65 (6/7.5)

Presentation

On her most recent visit her refraction was now:

R: +1.25/-2.00 x 85 (6/9)

L: +1.50/-0.75 x 80 (6/9)

Ultrawide field retinal scanning with the Optos Daytona (figure 1) and swept source OCT assessment with the Topcon Triton suggested hazy media, but a normal arrangement of the macula, retina and retinal nerve fibre layer (RNFL). We suspected posterior capsular opacification (PCO).
