An Important Issue in Ophthalmology

Ocular examinations, interventions, and surgeries are the most frequent medical aids in the United States and the world. Ocular interventions are also the most delicate and sensitive operations during which any fine unwanted movements can cause major ocular injuries. Thus, successful ocular interventions need motionless and fixed eyeballs. On the other hand, there is no harmless and safe method for fixation of the eyeball, and recent methods such as suturing the eyeball to the skin and maybe the eyeball with sharp instruments lead to major irreversible consequences such as eyeball rupture, ocular infections, and ophthalmitis. Some fixation methods need someone to keep the eyeball fixed, which occasionally is unsuccessful due to unwanted movements of the eye. Therefore, there is a major need for safe fixation of the eyeball without any adverse events and preventing unwanted post-operation consequences. Ocular disinfection during the intervention is also needed to prevent ophthalmic infection and reduce healing time.

Innovative solution

Ocusur, standing on the shoulders of innovative minds, have invented an ophthalmology surgical patent “Ocular speculum with the capability of fixation of the eyeball” for safe fixation of the eyeball for short-term and long term fine ocular examinations and interventions. The invention is registered as a provisional patent in USPTO that could provide safe fixation of the eyeball with less necessary handling, leading to stable conditions for ophthalmologists and surgeons. The patent also prevents ocular post-operation infections and ophthalmitis by decreasing ocular injuries and rinsing disinfecting agents during the surgeries. The mentioned patent also retracts the eyelids in order to expose the examination and intervention area. Two forms of the invention are going to be manufactured and marketed, including multi-use form and a disposable one. The disposable form of the patent could usually be used in clinics and medical ophthalmology offices and also in operation rooms, The while multi-use form could mainly be used in hospitals and clinics.

Ophthalmology Statistics in Brief

Eye care and technology development are good investments. An improved understanding of the scale of eye care needs is critical for effective planning in making policies and related industries. Here, there are some statistical estimates on visual impairment extracted from the World Health Organization (WHO) Reports. However, accurate estimates of the global magnitude of eye conditions are lacking. Globally, at least 2.2 billion people have a vision impairment, 312 million (95% credible intervals (CrI), 265 million to 369 million) aged under 19 years with myopia in 2015, 76 million (95% CrI, 51.9–111.7) people (40 to 80 years of age) with glaucoma in 2020, 2.5 million people of all ages with trachomatous trichiasis in 2019, 1.8 billion (confidence interval [CI], 1.7–2.0) people of all ages with presbyopia in 2015, 146 million adults with diabetic retinopathy (the global prevalence of any diabetic retinopathy (34.6%)) 195.6 million (95% CrI, 140–261) people aged 30 to 97 years with age-related macular degeneration in 2020, and 188.5 million people with mild vision impairment in which the causes are unknown. In 2010, WHO estimated that among 285 million visually impaired people, 39 million were blind, and 80% of them were avoidable. According to estimates of WHO, the global annual incidence of ocular trauma is around 55 million and worldwide blindness in 1.6 million people is due to ocular trauma.

         Why is Eyeball Fixation important? 

To do the best procedures in ophthalmology sensitive operations, a fine fixed status of the eyeball is needed. The non-fixed eyeball can cause major injuries in different ocular surgeries.
A small area of the ocular operations and globe shape of the eyeball makes the fixation hard for surgeons and in some cases, it is needed to hold the eyeball with fingers in which there are some interfering issues such as physical disturbance for such non-professional fixation method. The most common complications of non-safe fixation of the eyeball in surgeries are:

  • Corneal injuries 
  • Scleral injuries 
  • Lens detachment
  • Retinal injuries
  • Ocular hemorrhages
  • Ophthalmitis (Endophthalmitis)
  • Injuries to ocular peripheral tissues
  • Blindness

 

Complications of Available Eyeball Fixation Methods

Retrobulbar blocks:
Local Complications such as  Globe perforation, retrobulbar hemorrhage, and damage to the optic nerve, and General Complications such as Transient or Permanent Diplopia, Severe Sneezing, Transient Hemiparesis, Brain Stem Anesthesia, Apnea, Tachycardia, Seizures, Hypertension, Respiratory Arrest, and Even Death.

Globe Fixation Rings: 
Eyeball fixation rings need someone, a practitioner, or a surgery assistant to hold the apparatus in a suitable position. The main complications are physical or spatial disturbance, Corneal and Scleral Damages, Eyeball Rupture, and Ophthalmitis.
