The condition of the ocular surface critically impacts visual outcomes from refractive and cataract surgery. To achieve results that meet patients' high expecta- tions, surgeons need to evaluate the ocular surface and treat OSD before performing preoperative measurements. In the PHACO study, Trattler et al. found that nearly 77% of patients evaluated for cataract surgery demonstrated fluores- cein corneal staining, with 50% having central corneal staining. 1 However, dry eye had been diag- nosed in only 22.1%. In a multicenter clinical trial, Epitropoulos et al. found that average K readings and anterior corneal astigmatism varied more in patients with increased tear osmolarity, resulting in significant Express centers in the U.K., patients completed question- naires one month after surgery (Schallhorn SC, data presented at 2014 AAO annual meeting). A manifest refraction close to plano was closely associated with 20/20 uncorrected visual acuity. As ex- pected, the greater the refractive error, the less likely the patient's uncorrected distance vision would be 20/20. Likewise, increasing postoperative cylinder reduced the likelihood of 20/20 vision. Consequently, patients with increased residual refractive error after surgery were less likely to be satisfied with their outcomes. Nearly 71% of patients with no residual error were very satisfied with their results compared with 66.3% with 1.00 D MSE and 51.9% with 1.50 D MSE. Further- more, 73.2% of those with no residual cylinder and 66.9% with 1.0 D cylinder were very satisfied, Ocular surface disease may be an overlooked barrier P atients have high visual expectations of laser vision correction and re- fractive cataract surgery. Although surgical and technologic refinements contin- ue to advance our capabilities, surgeons need to address ocular surface disease (OSD) to deliver the results patients expect. Postoperative satisfaction Residual refractive error is a major driver of patient dissatisfaction because of its impact on visual acuity and quality of vision. In a study of more than 4,970 eyes (2,585 patients) un- dergoing refractive lens exchange with multifocal IOLs at Optical Practice pearl: Untreated ocular surface disease (OSD) associated with refractive surgery can lead to worse refractive outcomes, im- paired vision, and reduced patient satisfaction. Properly diagnosing and managing OSD, before surgery or if it develops after surgery, is critical to providing the best care and meeting patient expectations. –Steven Schallhorn, MD EyeWorld September 2016 Click to read and claim CME credit
