Cataract Surgery: Incidence of Posterior Vitreous Detachment on Quality of Vision and Reading Speed
Narrative Responses:
Purpose
To evaluate the incidence of posterior vitreous detachment (PVD) after phacoemulsification using optical coherence tomography (OCT) and to determine if it causes less quality of vision especially reading speed using a tablet quality of vision test.
Methods
OCT and a tablet quality of vision test were performed preoperatively in 50 patients with cataract. Patients underwent an uneventful phacoemulsification small incision surgery and implant of foldable intraocular lens (IOL). During Postoperative control day 7, 30 90 an OCT and tablet quality of vision test and reading speed calculation were repeated and compared with the preoperative tests.
Results
PVD was noticed in 29 eyes (58%) at month 1 and 35 (70%) at month 3. PVD influenced the quality of vision and especially reading speed was affected. Reading speed was often characterized with several disturbing interruptions and hesitation due to the fluctuation of the detached posterior vitreous.
Conclusion
Increase of PVD after cataract surgery was observed using the OCT. Postoperative quality of vision was measured, results were presented in percentage and difference between patients with PVD and without PVD was calculated. Reading speed and critical print size were calculated and compared.
