The authors describe a case of a keratoconic patient with Intacs fitted with a high-Dk piggyback contact lens system.
A 41-year-old man presented to the clinic 1 week after Intacs surgery for keratoconus with complaints of poor visual acuity (VA) and monocular polyopia OU. The patient was corrected to 20/30 in both eyes with rigid gas permeable contact lenses but could not tolerate the lenses for more than 8 hours OD and 2 hours OS. The patient was then successfully fit with a high-Dk piggyback contact lens system.
The patient was able to wear the piggyback contact lenses comfortably 12 to 18 hours per day and was corrected to 20/25 OD, 20/30 OS, and 20/20 OU.
Patients with Intacs for keratoconus may require a combination of soft and rigid contact lenses for the best possible VA. Contact lens fitting with a high-Dk piggyback contact lens system can provide optimal comfort, corneal health, and VA for patients with Intacs for keratoconus.

    ABSTRACT: Competing in the technology marketplace in the 21st century will require constant adaptation to shifting market demands. The most successful organizations will have an environment where creativity and innovation are occurring consistently at all levels of the organization, and in all functions. This paper discusses how complex adaptive systems can be seen as a model for adaptive organizations and postulates specific healthy (adaptive) and dysfunctional (maladaptive) attributes consistent with complexity concepts. Theoretical concepts are deconstructed to real world strategic approaches. An ongoing organizational assessment and intervention is summarized as evidence that these concepts have validity in the creation and sustenance of organizational innovation and vitality

    ABSTRACT: Purpose of review: The use of Intacs as a therapeutic modality in contact lens intolerant patients with mild to moderate keratoconus is increasingly gaining acceptance in the ophthalmic community. Recent findings: During the past year we have gleaned significant new information about patients who are appropriate candidates, the location and relative placement of segment sizes and long-term safety and stability after Intacs placement. Another new and exciting development which will make this procedure safer and more commonly acceptable is the use of the femtosecond laser to create the channels to insert the Intacs, which has been described for the first time this year. This technology allows for accurate depth of inserting, improved outcomes and less complications due to superficial placement. New reports about Intacs revision surgery also allows us to retreat many patients who would otherwise have been considered surgical failures. Summary: The new advances described this past year will improve outcomes and ultimately contribute to an increase in the amount of physicians performing this procedure and the number of patients requesting it.

    ABSTRACT: Tomris Sengor, Sevda Aydin Kurna, Suat Aki, Yelda ÖzkurtFatih Sultan Mehmet Training and Research Hospital, Istanbul, TurkeyBackground: The aim of the study was to examine the clinical success of high Dk (oxygen permeability) piggyback contact lens (PBCL) systems for the correction of contact lens intolerant keratoconus patients.Methods: Sixteen patients (29 eyes) who were not able to wear gas-permeable rigid lenses were included in this study. Hyper Dk silicone hydrogel (oxygen transmissibility or Dk/t = 150 units) and fluorosilicone methacrylate copolymer (Dk/t = 100 units) lenses were chosen as the PBCL systems. The clinical examinations included visual acuity and corneal observation by biomicroscopy, keratometer reading, and fluorescein staining before and after fitting the PBCL system.Results: Indications for using PBCL system were: lens stabilization and comfort, improving comfort, and adding protection to the cone. Visual acuities increased significantly in all of the patients compared with spectacles (P = 0). Improvement in visual acuity compared with rigid lenses alone was recorded in 89.7% of eyes and no alteration of the visual acuity was observed in 10.3% of the eyes. Wearing time of PBCL systems for most of the patients was limited time (mean 6 months, range 3–12 months); thereafter they tolerated rigid lenses alone except for 2 patients.Conclusion: The PBCL system is a safe and effective method to provide centering and corneal protection against mechanical trauma by the rigid lenses for keratoconus patients and may increase contact lens tolerance.Keywords: piggyback contact lens, keratoconus, irregular astigmatism
