GlobalCONTACT: A nice point to conclude with an outlook for the future. What is your prognosis for the industry for the next ten years?

FITTING BACKGROUND Geometry
Speed Date – CL-SAG meets OC-SAG Observations and findings from the Groenhof-Study. Part I/2 This article reports on a clinical study analyzing soft lens fits in a large contact lens practice in the Netherlands. Previous publications in this journal and elsewhere have questioned the method currently utilized to fit soft lenses. As a general understatement, central keratometry values appear to be not very efficacious for predicting the way soft lenses behave on-eye. The article ‘Myth or Fact’ in GlobalCONTACT 3_2013 covered these limitations in detail. By Eef van der Worp, Joost Hulscher Furthermore, the effect that soft lenses may have on the ocular

New soft multifocal contact lens for presbyopia The New “NaturalVue Multifocal 1Day” by Visioneering Technologies Incorporated (VTI) debuts from HQ in Alpharetta, Georgia, USA A new soft multifocal contact lens emerged first week of March 2015 at Atlanta's SECO convention. The SECO event is the annual meeting of the Southeastern Congress of Optometry, the largest yearly convention of optometrists in the world and is unmatched. A limited roll out of the “NaturalVue Multifocal 1 Day” to a select group of eye doctors was begun at Morton's Steak House during an evening dinner served in downtown Atlanta. Over the proceeding months optical practices over the southern United States will gain experience with these lenses. Fitting of the lenses is specific and unique with higher performance results promised. By Tom Baugh This daily disposable contact lens uses one universal add for an 89% fit success rate with adds effective from +0.75 to +3.00 D. The multifocal uses an extended depth of focus provided by patented Neurofocus Optics (TM) technology. The add is called “center distance” with a center base curve that measures 8.3mm, in a 14.5mm diameter one size. Obviously, this is where the patented “magic” of the universal add occurs. Initial lenses will only be in minus distance spheres from -0.25 to -6.25.

THE LESSONS WE CAN DRAW FROM THIS ARE TWOFOLD.
Firstly, a lathe-cut lens can compete with a moulded lens on comfort when fitted to a smaller or larger cornea than standard.
These corneae account for over 20% of all eyes. Secondly, not all lathe cut lenses are the same. In this study, the older lens (Design 1) clearly underperformed against the two other. Successful speciality labs continue to evolve and
grow, and, just like their larger competitors, continually upgrade their product in line with improvements in lathing technology and topographical data.

REPORT A different world
On the go The contact lens market in China is growing More than two thirds of all optical products sold in Europe and the USA come from China. This also applies to contact lenses. Up to now, mainly standard products have been available on the market in various qualities. The Chinese domestic market is also becoming more and more interesting due to the increasing purchasing power of the approx. 1.3 billion Chinese. The market for customized contact lenses is of particular interest. But anyone who wants to break into this market will have to do so in the Chinese language. ContactlensWORLD, a new business magazine from the Chinese subsidiary of the Ratingen Publishers Group in Xi’An, is aimed at the domestic market in China, designed to help bridge the information gap between manufacturers and fitters.

Contact lenses in forensics Forensic clues as part of an autopsy The question whether contact lenses could provide relevant evidence about an unexplained fatality remained unanswered for quite some time. However, it has now become an important issue in forensic science. In the meantime, investigating authorities, too, have come to realize that the examination of a contact lens may help to answer forensic questions â€“ with an experienced contact lens specialist assessing stained or damaged lenses, particularly after a crime or unexplained fatality. Dr. Hans-Walter Roth (Ulm) discusses some key cases from the wealth of forensic experience of the Institute for Scientific Contact Optics in Ulm. By Dr. Hans-Walter Roth

may help with the identification.
CASE 1: PLANE CRASH More than 280 people were killed in a plane crash in Malaysia. The identification of the corpses proved difficult, but one victim wore soft contact lenses with -9.50 D and could thus be identified. Relatives had informed the authorities about this particularity.
CASE 2: UNIDENTIFIED HANG GLIDER A 21-year-old man crashed while hang-gliding in Tyrol. He died on his way to hospital and had no ID-card with him. The accompanying emergency doctor noticed that he was wearing RGPs.

CASE 3: SEARCHING FOR OFFENDERS A girl is badly hurt in a fight between adolescents. The aggressors were able to run off before the police arrived. However one of them had lost his contact lens during the fight, which was discovered by forensics during the search of the crime scene. The local ophthalmologist was able to identify the owner of the lens because it was a customized lens for a keratoconus.

person wearing contact lenses could see adequately at the time of the accident. Thus it is important to check at the autopsy whether the lenses are still in place, have fallen out because of the accident or were not worn in the first place. This can be relevant for insurance purposes, especially after an accident involving severe injuries or fatalities. If someone who is supposed to drive with a vison correction aid is not wearing it, the person is considered unfit to drive and he is not covered by his insurance. The fitness to drive can also be impaired if the lenses have been worn for too long a time. This results in a cornea edema and reduced sensitivity to contrast and glare, which are common causes of accidents at night-time. After a fatality, however, no relevant statement can be made since especially post-mortem increased pachymetric values do not indicate how long the lenses were worn.

CASE 4: UNSUITABLE CONTACT LENSES After a night time car crash following a visit to a disco, an ophthalmologist was consulted to see if he could throw light on how the accident happened. The emergency doctor noticed that the driver's iris had an unusual structure. The reason soon became apparent: at the time of the accident the dead driver had been wearing crazy lenses. Examination in the contact lens in the laboratory revealed that the tinted lenses had no refractive power. However, according to his ophthalmologist, the driver had an ametropia of -1.50 D and was certainly not fit to drive without his vison correction aid. The determined blood alcohol level of 3.1 thus became Fig. 4: Massive amount of dust on a soft contact lens following a gas explosion

CASE 5: BULLET WOUND A dead man was found lying on a carpet with a bullet wound to his temple. Both eyes were wide open. The examination of the residual gunpowder revealed that the gun must have been directly touching the manâ€™s temple when the fatal shot was fired. Traces of gunpowder were found on the half-closed eye lids, on the conjunctiva not covered by the lenses as well as on the front faces of the lenses. This substantiated the evidence that somebody else must have been involved because in case of suicide with a gun, the victim's eyes would have been closed.
CASE 6: TIME OF DEATH A 23-year-old woman who had been missing for some time was found dead in a forest in midsummer. The eyes of the Fig. 5: Gunpowder residue and soot particles on a hard contact lens from a

death was thus deemed to have been around this time. The date of death can also be estimated if algae or fungi start growing on the outer side of lenses still in the eye. Depending on the moisture and temperature of the surroundings, it takes about twelve days in summer for the lenses to be covered with a single-layer of algae. Fungi that grow on soft contact lenses after the movement of the eyelids has stopped can also indicate the time of death. In case of doubt their growth rate can be simulated in the laboratory using germs taken from the surface of the lens.
CASE 7: DETERMINING THE TIME OF THE OFFENSE In a remote forest area a female corpse was found. The person had been missing for several days. The police found a soft contact lens close to the body that might have fallen out of the left eye at the time of the crime. The right contact lens was still in place. Both lenses were covered with Fig. 6: Reddish sand and dust particles from a tennis court made it possible to

Table 2 gives an overview of the most important findings such as material damage after the assault, residues on the lens surface, algae and fungi. Thorough photo documentation of the evidence with a digital camera is the minimum requirement for the assessment of a contact lens from a forensic point of view. If algae or fungi are found, their growth rate can be determined in an incubator at ambient temperature from which a time frame for the time of death can be calculated.

Until recently! All schools and the big hostel for blind children were not damaged by the last earthquake and are still in use. At this moment as shelter for victims who lost their houses.

1. If I didn’t do this job, then… I would never have had the opportunity to get to know the friends and colleagues I enjoy working with now and for so long. 2. The best thing about this job is…the chance to make a difference… to people and their businesses. 3. In this job it is not difficult to… find enrichment through understanding cultural differences, appreciate the value others are willing to share with you and to be open to fresh thinking every day. 4. The last time I was disappointed with my job was… when I fell so ill that I couldn’t travel to see my clients/friends. 5. Using social media for the company means… employing an efficient and focused method for client communications! Public social networks are not the best place for client specific discussions. We want our customers to access technology based responses specific to their individual needs, so we utilize web-based tools and a specific 'dac support’ system to get direct responses and action that meet their specific requirements. Simply put, it’s an extension of the 'personal touch’ we like to give in all of our interaction with clients and suppliers alike 6. Professional/trade journals are… a wonderful source of finding my inner inspiration, helping me to focus my experiences and how to best share that with our industry and to learn from other’s what is to come! 7. I was surprised that… I would continue learning long after I finished school. 8. For me talking with customers is… probably one of the best ways to understand what I can do to make my job more effective. 9. When we introduce a new product… it’s so much fun to see the reaction of the clients. Being innovative is a great way to get the most out of your product or service and one of the most exhilarating to be a part of. We need to keep moving forwards if we want to keep ahead of the new challenges. 10. I can see why a product is going to be successful by… the passion and enthusiasm shared by everyone involved. That’s a sure-fire way to see that everyone’s confidence is well placed in the efforts leading up to that moment and goes a long way to ensure a products success. 11. When I think about those who work for me, I am happy that… I have them on my team! I value their experiences and the feedback they provide me. Without they’re efforts, I could not be as effective at my job as I am. 12. A day is perfect when… the client gives repeat orders. 13. The most insane thing about my job was… visiting 8 countries in 5 days! 14. I cannot live without… a Whiskey….What can I say, I’m Scottish, so it’s in my blood! 15. My greatest wish is… that there would be more peace in the world and that all eye corrections were made with great contact lenses and IOL’s!
