Purpose:
To evaluate the benefits of routine use of preoperative spectral optical coherence tomography (OCT) examination in cataract patients.
Setting:
Observational nonintervention prospective study. 100 eyes of 100 patients that had cataract surgery done at the Clinic of Ophthalmology at the University Hospital Ostrava from March to May 2011 were randomly chosen and included in the study. 38 males and 62 females were included, the age was 34 88 years (median 74).
Methods:
All the patients had spectral OCT (Heidelberg Spectralis) RNFL and fast macular scans performed, BCVA pre and 1 week postoperatively was evaluated. Preoperative fundus biomicroscopy examined by general ophthalmologist and OCT findings evaluated by vitreoretinal and glaucoma specialists were compared. The implications were discussed with the patients.
Results:
Preoperative BCVA was 6/9 to 0,5/60 (median 6/12), postoperative BCVA was 6/6 1/60 (median 6/9). 28 eyes had macular pathology on fundus biomicroscopy in contrast to 35 eyes with pathology on OCT. 12 eyes had glaucomatous changes on optic nerve head on fundus biomicroscopy in contrast to 25 eyes with pathologic or borderline changes on RNFL on OCT. 27 eyes had pathologic or borderline findings on OCT only, while only 6 eyes had pathologic findings on fundus biomicroscopy only. All the patients appreciated OCT interpretation according to pathologic findings and relation to BCVA.
Conclusions:
OCT can detect subtler changes in RNFL and/or macula region than routine fundus biomicroscopy. OCT provides the surgeon with additional information which may have impact not only in cataract surgery and premium IOL implants but in routine cataract surgery as well. Therefore it should be considered as a standard preoperative procedure prior to cataract surgery. FINANCIAL DISCLOSURE?: No
