Objective.
To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity.
Methods.
In this prospective, observational, and nonconsecutive case series study, a total of 32 eyes of 29 patients are diagnosed with posterior capsule opacification after age-associated cataract were analyzed.
Patient examination included age, the period after cataract surgery, logMAR best corrected visual acuity (BCVA), and OSI.
Results.
We found a significant decrease in the BCVA and increase in the OSI with the development of posterior capsule opacification.
The decrease of BCVA was statistically correlated with the increase of OSI (r=0.812, P<0.01).
In patients who reported visual disturbances without decreased visual acuity, OSI decreased to <1.3 and subjective symptoms were resolved in all cases although there was no significant improvement in visual acuity after laser capsulotomy.
Conclusions.
The results of our study showed that OSI is also a useful parameter for objectively evaluating posterior capsule opacification.
OSI may help predict laser capsulotomy in patients who report visual disturbances without decreased visual acuity.
