![]() While adapted pathogens have evolved virulence effectors that can circumvent PTI, plants also deploy disease resistance ( R) genes, primarily encoding nucleotide-binding LRR proteins, which mount effector-triggered immunity (ETI) 3, 4, 5. ![]() In plants, pattern-recognition receptors (PRRs), such as leucine-rich repeat receptor-like kinases (LRR-RLKs) and LRR receptor proteins (LRR-RPs), specifically recognize microbe-associated molecular patterns (MAMPs) as non-self molecules, leading to the activation of pattern-triggered immunity (PTI) to limit pathogen proliferation 1, 2. Innate immunity is an evolutionarily conserved front line of defense across the plant and animal kingdoms.

Optical and visual impact of tear break-up in human eyes. We make ocular surface optimization part of the discussion for each of our Raindrop patients, and they are quite comfortable and willing to invest in getting the best possible result.ġ. ![]() In our practice, we find that optimizing the ocular surface requires very little additional chair time and does not delay surgery. Early interim data show that patients who had dry eye treatment before and after surgery have improved tear break-up time and better initial distance vision. The study group had LipiFlow (Johnson & Johnson Vision) thermal pulsation treatment for MGD before surgery, as well as high-dose DHA/EPA omega 3 supplements (Dry Eye Omega Benefits, PRN) and artificial tears to optimize the ocular surface both before and after surgery. Half of the subjects were randomized to undergo ocular surface optimization and half to proceed without treatment. We believe that early optimization will provide good visual recovery after surgery. 2 We have enrolled 40 patients with mild to moderate dry eye. My colleagues and I are currently carrying out a investigator-driven clinical study of Raindrop subjects with optimized and non-optimized ocular surfaces. Oftentimes, they are on other medications, and they spend long hours using computers. Transected nerves in the cornea can cause neurotrophic dry eye after surgery-a problem made all the worse by untreated preexisting ocular surface problems.įinally, patients seeking treatment for presbyopia are generally in their 40s and 50s, so they tend to be drier and have some meibomian gland dysfunction (MGD). Irregular tear film can negatively affect retinal image quality 20% to 40%, 1 making it necessary to achieve a healthy tear film both pre- and postoperatively.Īnother reason to optimize the ocular surface before surgery is that the Raindrop (ReVision Optics, Inc.) procedure involves creating a LASIK-like flap, typically even deeper than traditional LASIK. ![]() For all refractive surgeries, including corneal inlays, patients benefit from a healthy ocular surface, so it is essential that we optimize the ocular surface before surgery.
