“…Recent reports suggest that photorefractive keratectomy induces a transient increase in the concentration of H 2 O 2 in the aqueous humor of treated rabbits (2,3), raising concern about the cataractogenic risk of an exposure to UV-laser or secondary radiation.…”

“…Apart from ectasias and regression, cataract is an important cause for poor vision following refractive surgery. [23] A large number of these patients present with symptoms of glare and reduced contrast. A characteristic increase in higher order aberrations (HOAs) and scatter are seen, suggestive of what can be termed as “preclinical” lens changes, which can be detected using newer diagnostic modalities such as Scheimpflug imaging and ray tracing.…”

“…[123] Patients' complaints include ghosting of images with increased glare and reduced contrast even before lenticular changes are clinically detectable. These symptoms, which are secondary to a subclinical cataract, can mimic post-LASIK regression.…”

Preclinical cataract masquerading as post-LASIK regression

The purpose of this case report is to bring forth a rare clinical scenario where preclinical cataract mimics post-LASIK regression and to describe the role of aberrometry in detecting higher order aberrations (HOAs) and early lens changes. A 36-year-old female presented with blurring of vision since 1 year after having undergone an uneventful LASIK surgery 3 years prior. Corneal topography and aberrometry were within normal limits. Although the lens was morphologically normal on slit lamp examination, increased HOAs and lenticular density were detected. Since there were no cataractous changes, the patient was advised regular follow-up. A year later, the patient had developed lenticular changes along with a further increase in aberrations and worsening of scatter on densitometry. Increase in aberrations and lenticular density may serve as a marker for cataract development before clinically detectable lenticular changes. This report shows how preclinical cataract can mimic post-LASIK regression with a change in spherical and cylindrical power of the eye. This could result in patients undergoing re-correction in eyes where the primary pathology is in the lens.
