Off the Cuff: Avesis is Latin for We Won’t Be Paying You

As much as I detest health care insurance, some providers are better than others. Then again, some are much worse than others—far worse.

A few years back, a vision care provider with a glib OD front man started coming to our state association meetings. He seemed sincere enough, so his reassurances about how much his company respected and wanted to work with optometry sold us. The plan covered state of Arizona employees, which sounded good to us, as we built a then brand-new practice.

So we initiated the credentialing process. When we requested a fee schedule, we were told that it was confidential and only provided to participating providers. Although warning bells rang in the distance, the explanation seemed sufficiently plausible to get past my typical New Yorker state of finely tuned BS detector.

We soon found out that the plan was not what we were told. Reimbursements were paltry, and dilated exams had to be justified, coded separately and were payable for state employees only. In this day and age that’s hard to believe, isn’t it? By the time we realized what we had stepped into, we had unpaid claims accumulating.

Although we hated to lose patients, we sent our notice of withdrawal from the plan and waited to be taken off the provider list. Today, well over a year later, more than a thousand dollars in legitimate claims remain unpaid, despite numerous calls and repeated empty promises. This past weekend, out to dinner with OD friends, we discovered that we’re not alone. A quick check of other local practices shows that this may be endemic. 

We will be filing a complaint with our state insurance commissioner, and now that I am sufficiently irritated, perhaps I’ll take it further. However, regardless of how this turns out, an important lesson was learned: If an insurer isn’t up front from the beginning, the relationship isn’t likely to have a happy ending.

The Safety of Soft Contact Lenses in Children
 
 
Researchers wrote that there is increasing interest in fitting children with soft contact lenses. They reviewed and collated data from a range of studies to estimate the incidence of complications, specifically corneal infiltrative events and microbial keratitis, in patients under the age of 18 years. Peer-review papers were identified using PubMed and the Web of Science. A broad range of studies are summarized, including large-scale epidemiological studies of contact lens-related complications, hospital-based case series, long- and short-term prospective studies, and multicenter retrospective studies.

Nine prospective studies representing 1,800 patient years of wear in 7- to 19-year-olds include safety outcomes. In three large, prospective studies representing between 159 and 723 patient years of soft contact lens wear in patients eight to 14 years, the incidence of corneal infiltrative events is up to 136 per 10,000 years. Data from a large, retrospective study show similar rates of corneal infiltrative events: 97 per 10,000 years in 8- to 12-year-olds (based on 411 patient years of wear) and 335 per 10,000 years in 13- to 17-year-olds (based on 1,372 patient years of wear). None of the prospective studies reported any cases of microbial keratitis. Five clinical studies where safety data were not reported constituted a further 493 patient years. One retrospective study found no cases of microbial keratitis occurred in 8- to 12-year-olds (411 patient years) and an incidence of 15 per 10,000 patient years in 13- to 17-year-olds (1,372 patient years)—no higher than the incidence of microbial keratitis in adults wearing soft contact lenses on an overnight basis.

Researchers concluded that the incidence of corneal infiltrative events in children was no higher than in adults, and in the youngest age range of 8 to 11 years, it might be markedly lower.

Scleral Topography Analyzed by Optical Coherence Tomography
 
 
Investigators wrote that a detailed evaluation of the corneo-scleral-profile (CSP) is of particular relevance in soft and scleral lenses fitting. As such, they used optical coherence tomography (OCT) to analyze the profile of the limbal sclera and evaluate the relationship between central corneal radii, corneal eccentricity and scleral radii. Using OCT (Optos OCT/SLO, Dunfermline, Scotland, UK), the limbal scleral radii (SR) of 30 subjects (11M, 19F; mean age 23.8D ± 2.0SD years) were measured in eight meridians 45 degrees apart. Central corneal radii (CR) and corneal eccentricity (CE) were evaluated using the Oculus Keratograph 4 (Oculus, Wetzlar, Germany). Differences between SR in the meridians, and the associations between SR and corneal topography were assessed.

Median SR measured along 45 degrees (58.0; interquartile range, 46.8mm to 84.8mm) was significantly flatter than along 0 degrees (30.7; 24.5mm to 44.3mm), 135 degrees (28.4; 24.9mm to 30.9mm), 180 degrees (23.40; 21.3mm to 25.4mm), 225 degrees (25.8; 22.4mm to 32.4mm), 270 degrees (28.8; 25.3mm to 33.1mm), 315 degrees (30.0; 25.0mm to 36.9mm) and 90 degrees (37.1; 29.1mm to 43.4mm). In addition, the nasal SR along 0 degrees were significant flatter than the temporal SR along 180 degrees. Central corneal radius in the flat meridian (7.83 mm ± 0.26mm) and in the steep meridian (7.65mm ± 0.26mm) did not correlate with SR. There was no statistically significant correlation between corneal eccentricity and scleral radii in each meridian.

With the OCT device used in this study, investigators were able to measure scleral radii in eight different meridians. They determined that scleral radii were independent of corneal topography and might provide additional data useful in fitting soft and scleral contact lenses.

Progression of High Anisometropia in Children
 
 
A retrospective study investigated the onset and rate of progression of high anisometropia in myopic children. Children younger than 13 years with anisometropia, myopia of more than 4.00D in the more ametropic eye and a difference in spherical equivalent refraction of 4.00D between both eyes were included. All children had a complete ophthalmologic examination, including measurement of visual acuity and cycloplegic refraction every three to six months for at least five years. Change in the spherical equivalent and the cylindrical error for both eyes, and changes in the difference in spherical equivalent refraction between both eyes were calculated for each patient at each visit. Linear, polynomial, logarithmic and exponential fitting models were tested for both eyes and for the anisometropic difference between both eyes. The regression line with the greatest R2 value was considered the best fit.

Sixty-three patients fulfilled the inclusion criteria. The more ametropic eye grew in a regular fashion during the first two years of life, followed by a rapid decrease in the rate of growth to almost stable levels after four years of age. The increase in myopia best fit a third-degree polynomial (cubic) model (R2=0.98). The less ametropic eye showed only a small increase in myopia during the follow-up period. The anisometropic difference between both eyes increased gradually during the first two years, then remained stable.

Investigators concluded that high anisometropic myopia progressed rapidly in the first few years of life before becoming stable.

Reichert Introduces Family of Digital Acuity Systems
Reichert Technologies launched three ClearChart digital acuity systems: the 4 Digital Acuity System, 4X Enhanced Digital Acuity System and 4P Polarized Digital Acuity System. The new family of ClearChart digital acuity systems offers a wide selection of optotypes and other special test charts. Optotypes include: 17 letter set, 8 letter set, Sloan, HOTV, Landolt C, Landolt C & O, Tumbling E and Children’s Optotypes, among others. Special test charts include astigmatic testing, fusion, phoria and binocular balance. Optotypes can be isolated, increased or decreased in size, and displayed in LogMar, Snellen or linear progression. The systems feature 24-inch, high-resolution, LED-backlit displays that are lightweight and cool running. The systems, which require no separate components or software, are free of moving parts, noisy fans and spinning hard drives. They can be configured for standard or mirrored viewing to accommodate refracting distances from 6 feet to 24.6 feet. Users can import images and videos by importing files from a USB drive.
