Gaze dynamics is the behavior of the human oculomotor system (head, neck, eyes) when the individual follows objects that draw their attention or that are relevant to the activity they are performing with their gaze. This is unique to each person, as each individual has a different way of looking.
When we introduced the concept of gaze dynamics, we talked about the need for an absence of restrictions in the visual environment so that a person can perform eye and head movements without any limitations. With the use of progressive lenses, gaze dynamics encounters limitations due to the lateral aberrations.
As developers of progressive designs, our aim is to find tools capable of analyzing gaze dynamics so that we can offer each person the progressive solution that best suits their individual visual needs.
Thanks to a Virtual Reality helmet we are able to obtain the gaze dynamics for each patient at far, intermediate and near distance. For this reason, we are providing the patient the possibility to keep their own gaze dynamics behaviour when wearing addition progression lens.

Contact lenses for irregular corneal is one of development method for management most of corneal disorders due to the corneal shape.
They have been summarized into 4 types:
1. Soft customized lenses
2. RGP corneal lenses
3. Hybrid RGP/soft
Soft Customized from its name we are customizing the lens basing on Base Curve–Diameter–material–over refraction basing on slit lamp examination with trial set and assessing the movement–rotation–centration–conformability-Visual acuity.
RGP the oldest design and here we letting the PMMA material to play a role of correcting the corneal shape by a little feather touch and its diameter range between 8-11 mm and its landing on the cornea.
Hybrid lenses the RGP from center and peripheral is soft skirt landing on the scleral and between the corneal and RGP part is a tear lens or space filled up with solution for neutralizing the irregularity and correcting the residual astigmatism.
Scleral lenses RGP lenses that landing on the scleral and it’s one of the best solution with dryness and it’s same as hybrid lenses depending on tear lens or the space between cornea and lens filled up with saline and it’s easier in removing and wearing.
Presentation ends with success and unique stories for different types of lenses and advanced case of keratoglobus–keratoconus–PMD–Post lasik Ectasia–post graft.
Alexia Martinez has completed his PhD at the age of 21 years from Polytechnic University of Catalonia (2006) and Master’s in Project Management from La Salle Universitat Ramon Llull (2016). She has worked in Institut Català de Retina (2007-2022) as optometrist performing tasks in the refractory area in consultation and ophthalmological diagnostic tests and tutoring final master's projects at Master’s in Project Management from La Salle Universitat Ramon Llull. She is Project Manager at Horizons Optical and Professor Project Management Course in Optics and Optometry at Universitat Politècnica de Catalunya.
The sales process of ophthalmic lenses has always been traditional, highly clinical and with little patient involvement. The patient is advised by the optometrist and has little margin for participation.
At Horizons Optical's User Experience Department we have found that being an active part of the final choice or even become part of the creation of the lens leads to a higher degree of satisfaction and adaptation. We believe that the incorporation of new technologies can provide new tools for the explanation, diagnosis and attractive sales of ophthalmic lenses while maintaining clinical rigour. These technologies allow increasing product personalisation and improving user experience, making the purchasing process much more agile and participative.
The purpose of this talk is to show the evolution of the user experience and how new technologies add value to both the optometrist and the patient who wants to purchase the product. We will show with examples how technological innovation is helping to transform the ophthalmic lens sales, focusing on the end user and carrying out more precise measurements for the personalisation of ophthalmic lenses.

He is skilled in refraction, patient care, education and counselling. He is also dexterous in instrumentations such as perimetry, pachymetry and optical coherence tomography as well as result interpretation. He is a public health enthusiast who has participated in several community health outreaches, giving health talks bordering on ocular health.
Dry Eye Disease is fast becoming a public health issue in eye care. Therefore, it is imperative for eye care professionals to be armed with the necessary knowledge geared towards improving the quality of life of every dry eye patient that walks into our practice. TFOS DEWS II defines dry eye disease as the following: “Dry eye is a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and hyper-osmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles.” Dry Eye Disease is multifaceted, thus the importance of diagnosing dry eye patients with the right kind of dry eye cannot be overemphasized as treatment approach for the two major kinds of dry eye disease differs. Understanding their pathophysiology, clinical presentation and management is a key to top-notch patient care. This poster presentation will shed light on the pathophysiology, risk factors, signs and symptoms, treatment, management of Dry Eye Disease as well as novel technologies and medications employed in the treatment of this disease. At the end of the poster presentation, eye care professionals would be armed with a gamut of knowledge required to have the Quality of Life (QoL) of dry eye patients significantly improved.
University of Cape Coast, Ghana

Ocular toxoplasmosis occurs as a result of infection with the Toxoplasma gondii parasite. It may be potentially sight-threatening. The disease usually presents with necrotizing retinitis as well as secondary choroiditis in one or both eyes, that occurs adjacent to a pigmented retinochoroidal scar. Retinal vasculitis and vitritis usually accompany this ocular condition. In immunocompromised patients, there may be atypical presentations and/or severe inflammation. A diagnosis of typical ocular toxoplasmosis can be made after a comprehensive clinical examination and may be confirmed with toxoplasma serology. The treatment of ocular toxoplasmosis usually involves oral pyrimethamine and sulfadiazine in addition to oral systemic corticosteroid. Other systemic antibiotics such as clindamycin and azithromycin may also be used to treat ocular toxoplasmosis. Herein is discussed a case of ocular toxoplasmosis, diagnosed and successfully managed in a nineteen-year-old African female.
Mbanaja Peacepaul Nkechinyere is a certified and licensed optometrist from Federal University of Technology Owerri, Imo state Nigeria. He worked in various institutions which include University of Port Harcourt Teaching Hospital, Alex Ekwueme University Teaching Hospital and presently in Niger-Delta University Teaching Hospital okolobiri Bayelsa state, Nigeria, has developed great passion for researches, health and well-being of people. This presentation centers on identification of low vision patients and provision of low vision rehabilitation services for better vision and well-being.
Statement of problem: Patients who have low vision, whether inherited or acquired, run the risk of developing mental and physical health issues, such as frequent falls, loneliness, social withdrawal, anxiety, worry and fear.
Aim: The study aims to identify persons who do not use low vision rehabilitation services and provide them with low vision rehabilitation services to increase independence and improve their quality of life.
Orientation: Patients with the best visual acuity in the better eye worse than 20/40 were identified as low vision patients in a study employing health record-based retrospective chart analysis. Patients with the best visual acuity in the better eye worse than 20/40 were termed low vision patients in a study employing health record-based retrospective chart analysis. The utilization of low-vision rehabilitation services across nine clinic locations was assessed. To investigate the characteristics associated with service utilization, logistic regression analysis was utilized.
Findings: Out of the 7752 low vision patients, 6197 do not use low vision rehabilitation Services, according to the findings and they had VA less than 20/200.
Significance: When visual acuity is moderate to severely compromised, patients are more likely to use low vision rehabilitation treatments.
