Misleading axial length measurements with the IOLMaster due to a dense posterior vitreous surface membrane and a macular edema in a diabetic patient

Exact biometry is an essential component in cataract surgery to obtain accurate refractive results . The IOLMaster® is a precise and common instrument to obtain axial length [2, 3, 4, 5]. We describe a case of a patient with diabetic retinopathy in which the IOLMaster® was not able to determine an axial length. Clear signals from a dense posterior membrane as well as from retinal pigment epithelium (RPE) and macular edema were received.
A 46-year-old female with severe proliferative diabetic retinopathy on both eyes was referred to our department. Vision was 20/25 in the right eye and 20/200 in the left eye. A combined vitrectomy with cataract surgery was planned, and axial length measurements were taken with the IOLMaster® (Vers.: 3.01.0294; Zeiss, Germany).
