A rapid and cost-effective method for monitoring proteins in tear-fluid is reported, which enables biomarker monitoring using contact lenses toward personalized mobile-health applications.

Patient satisfaction after modern day cataract surgery requires excellent surgical technique but increasingly demands superior refractive outcomes as well. In many cases, there exists an expectation from patients, as well as surgeons, to achieve emmetropia after cataract surgery. This is particularly true in patients electing premium intraocular lens technology to correct astigmatism and presbyopia to minimize spectacle dependence. Despite continued advances in preoperative and intraoperative diagnostics, refractive planning, and surgical technology, residual refractive error remains a primary source of dissatisfaction after cataract surgery. The need to enhance refractive outcomes and treat residual astigmatic or spherical refractive errors postoperatively becomes paramount to meeting the expectations of patients in their surgical outcome. This article reviews the potential preoperative and intraoperative pitfalls that can be the source of refractive error, the various options to enhance refractive outcomes, and potential future technologies to limit residual refractive error after cataract surgery.

As cataract surgery continues to evolve, the intraoperative small pupil continues to pose challenges to even the most experienced cataract surgeon. Several steps can be taken preoperatively to decrease the chance of intraoperative miosis. Even so, the problem of miosis during cataract surgery remains a relatively common occurrence. This paper discusses many steps, both preoperative and intraoperative, that can make surgery technically easier and safer, thus maximizing the postoperative outcomes and patient satisfaction. Complications associated with small-pupil cataract surgery, risk factors for intraoperative miosis, the preoperative and intraoperative management of the small pupil during cataract surgery, and postoperative care are reviewed.
