Abstract Background To compare the anterior surface roughness of two commercially available posterior chamber phakic intraocular lenses (IOLs) using atomic force microscopy (AFM). Methods Four phakic IOLs were used for this prospective, experimental study: two Visian ICL EVO+ V5 lenses and two iPCL 2.0 lenses. All of them were brand new, were not previously implanted in humans, were monofocal and had a dioptric power of − 12 diopters (D). The anterior surface roughness was assessed using a JPK NanoWizard II® atomic force microscope in contact mode immersed in liquid. Olympus OMCL-RC800PSA commercial silicon nitride cantilever tips were used. Anterior surface roughness measurements were made in 7 areas of 10 × 10 μm at 512 × 512 point resolution. The roughness was measured using the root-mean-square (RMS) value within the given regions. Results The mean of all anterior surface roughness measurements was 6.09 ± 1.33 nm (nm) in the Visian ICL EVO+ V5 and 3.49 ± 0.41 nm in the iPCL 2.0 (p = 0.001). Conclusion In the current study, we found a statistically significant smoother anterior surface in the iPCL 2.0 phakic intraocular lenses compared with the VISIAN ICL EVO+ V5 lenses when studied with atomic force microscopy.

Nervous Structure

Since the communication above referred to was presented to the Royal Society, I have made a very minute dissection in alcohol of the whole nervous system of the young heifer’s heart. The distribution of the ganglia and nerves over the entire surface of the heart, and the relations of these structures to the blood-vessels and muscular substance, are far more fully displayed in these preparations than in any of my former dissections. On the anterior surface, there are distinctly visible to the naked eye ninety ganglia or ganglionic enlargements on the nerves, which pass obliquely across the arteries and the muscular fibres of the ventricles from their base to the apex. These ganglionic enlargements are observed on the nerves, not only where they are crossing the arteries, but where they are ramifying on the muscular substance without the blood-vessels. On the posterior surface, the principal branches of the coronary arteries plunge into the muscular substance of the heart near the base, and many nerves with ganglia accompany them throughout the walls to the lining membrane and columnse carneæ. From the sudden disappearance of the chief branches of the coronary arteries on the posterior surface, the nervous structure distributed over a consider­ able portion of the left ventricle is completely isolated from the blood-vessels, and on these, numerous ganglionic enlargements are likewise observed, but smaller in size than the chains of ganglia formed over the blood-vessels on the anterior surface of the heart. In the accompanying beautiful drawings, Mr. West has depicted with the greatest accuracy and minuteness the whole nervous structures demon­strable in these preparations on the surface of the heart. But the ganglia and nerves represented in these drawings constitute only a small portion of the nervous system of the heart, numerous ganglia being formed in the walls of the heart which no artist can represent. It can be clearly demonstrated that every artery distributed throughout the walls of the Uterus and Heart, and every muscular fasciculus of these organs, is supplied with nerves upon which ganglia are formed.

First Case

Trypan blue is common in visualizing the anterior capsule during cataract surgery. Inadvertent staining of the posterior capsule during phacoemulsification is a rare complication and there are few reports in the literature. The proposed mechanism of posterior capsule staining in previous reports includes a compromised zonular apparatus or iris retractors facilitating the posterior flow of trypan blue. We report the first case of trypan blue staining of the posterior capsule associated with the “Argentinian flag” sign. In our case, the “Argentinian flag” allowed the trypan blue to seep between the posterior capsule and the lens, staining the anterior surface of the posterior capsule.

Associated Diseases

Glaucoma and ocular surface disease (OSD) are often concomitant disorders (OSD is the consequence of a tear film dysfunction that may be due to several conditions). The aims of the paper are to suggest a sequence of diagnostic tests easy to perform in daily practice, both subjective and objective, to detect the onset of the OSD; and, second, to propose how to prevent and, if the case, how to manage the OSD. Briefly, tear film break-up time (TF-BUT) and corneal/conjunctival staining are suggested to detect the main signs of OSD. In terms of therapy, the long-term exposure to benzalkonium chloride (BAK) should be minimised, preferring non-BAK-preserved or BAK-free glaucoma medications, where available, as well as fixed combinations. The treatment of associated diseases of the anterior surface may reduce signs; use of non BAK-preserved tears may reduce symptoms.

T., 55 years old, choked on a fish bone while eating. After 2 days, she was admitted to the ENT clinic with complaints of sore throat, hoarseness, sharp difficulty in swallowing and breathing. The general condition of the patient is severe, the neck is enlarged due to edema of soft tissues, the skin is pale, on the anterior surface of the chest there are massive subcutaneous hemorrhages. The patient retains a forced position, cannot lie on the couch on her own. Palpation of the neck and interscapular region causes severe pain. Temperature 39.3 .

Serious Disease

Introduction and purpose. The main manifestation of eyelids, tear ducts, and orbits disorders is a dry eye disease considered as a serious disease that affects the quality of life. Nowadays, one in ten people worldwide faces this disease. Increased workload, development of multimedia technologies, hypodynamia, and environmental degradation are the main modern causes of the disease. Material and methods. In this work, we used an experimental model of dry eye in rats with the development of inflammation of the anterior surface of the eye. Alkali burns were used to develop inflammation. A fluorescein test performed immediately after alkaline erosion and on days 1, 5, and 10 after burns revealed a gradual increase in corneal epithelialization and vascularization. Results. One day after induction of inflammation, there was a dramatic and statistically significant increase in tear production in experimental rats. By the seventh day, tear production declined to the control level with a subsequent tendency to decrease tear production. Conclusions. In the group of rats with inflammation of the anterior surface of the eye that received polarized red-light therapy, there was no significant decrease in tear production on day 7, which may be indicative of a possible anti-inflammatory effect of light therapy under these conditions.
