Abstract Details


The present pilot study aims to investigate the influence of preoperative Intense Pulsed Light therapy on ocular surface parameters after cataract surgery in presbyopic subjects


Clinica OftalVist Valencia


Twelve eyes from 6 presbyopic patients were included in the pilot study. Six eyes were treated with Intense Pulsed Light (ThermaEye) 7 days before cataract surgery and the fellow eye was used as control. Symptoms including OSDI and DEQ-5 questionnaires, Osmolarity (I-Pen® Osmolarity System IMED PHARMA), tear meniscus height (TMH), fluorescein conjunctival, corneal staining and tear break up time (TBUT), infrared meibography (Topcon DC-4) were performed 7 days before and 7 days after cataract surgery. Differences were considered statistically significant at p ≤ 0.05 level


OSDI and DEQ-5 questionnaires scores improved significantly after IPL, (p=0.04 and p=0.05, respectively). No change occurred for the control group after surgery for both questionnaires. Osmolarity significantly decreased for the IPL group (p=0.031) and was significantly lower than control group post operatively (p=0.037). TMH did not show significant change before and after surgery for either group. Fluorescein staining did not change in either group after surgery. TBUT increased significantly for the IPL group (p=0.043) whereas no changes occurred in the control group (p=0.31). Infrared meibography did not show changes in Meibomian gland pattern in either group (P> 0.05).


IPL therapy positively influenced DED symptoms, osmolarity values and tear film stability after cataract surgery. TMH values, ocular surface staining and Meibomian glands patterns remained unchanged. IPL therapy prior to cataract surgery seems to be a promising technique to improve postsurgical outcomes.
