A fifty-eight year old male presented to the clinic for a scleral lens consult in the right eye.
POHx: Penetrating keratoplasty in the right eye 20+ years ago. He had previously failed with corneal GPs (comfort, frequent lens dislocation) and hybrid lenses (poor comfort, inability to remove lens at end of day). Current commercial soft lens wearer in left eye.
PMHx: Unremarkable
8 hours of continuous wear with improved vision versus spectacles and improved comfort and handling versus most recent hybrid lenses.
OD:pl -4.00 x 100; 20/50
OS: -2.25 -2.75 x 100; 20/20
Anterior Segment:
OD: PKP; centrally clear with minor inferior-nasal neovascularization; bulging inferior graft (see topography)
OS: minor thinning; (-) Vogt’s Striae, (-) apical scarring
Axial/Sagittal Curvature (Front)
CL Fitting
Patient wished to continue in soft lens in the left eye. A scleral lens fitting in the right eye was performed.
Trial Lens
OD: Custom Stable Elite 16. 8/ 7.18 BCR/ -6.00 / LCZ: STD / SLZ: +6/-4
- Fitting notes after 30 minutes: Central clearance ~200, 1 mm area of touch at inferior nasal host/graft junction (see OCT); adequate limbal clearance; 360 scleral alignment; Over-refraction -2.25 sph; VA 20/15
Increase mid-peripheral clearance; order 1 step steep in Limbal clearance zone.
OD: Custom Stable Elite 16. 8/ 7.18 BCR/ -8.25 / LCZ: -1 (1 steep) / SLZ: +6/-4
Final Fitting Notes (after 6 hours of lens wear): Central: clearance 200 microns, ~75 microns clearance over inferior nasal host/graft junction (see OCT); adequate limbal clearance; 360 scleral alignment; over-refraction plano; VA 20/15
The lens was sent home with the patient and he was instructed to return for a 1 week follow-up. At 1 week the fit and vision were unchanged. The patient noted his vision was the clearest it had been in 30 years. He also reported that the scleral lens was more comfortable and provided superior vision compared to his previous corneal GPs and hybrid lenses. He went on to say that the scleral lens was more comfortable than the commercial soft lens in the left eye. The same findings and comments were true at the 1 month follow-up. He plans to return to clinic for a scleral lens fitting in the left eye in the near future.
Axial/Sagittal Curvature (Front)
Additional Comments
The Limbal Clearance Zone of the Custom Stable lens contains a powerful reverse curve to increase limbal clearance while allowing a smooth transition from the Optic Zone to the Scleral Landing Zone. This zone can be easily manipulated with the step system to increase or decrease limbal, mid-peripheral, and central corneal clearance. In this case, the diagnostic lens showed adequate central clearance, however, the host/graft junction, located in the mid-periphery of the lens, exhibited touch. Ordering a lens that was 1 step steep in the Limbal zone allowed for clearance of the host/graft junction while maintaining an acceptable level of central clearance.

We are proud to promote Amigos Eyecare, a student led organization at Pacific University College of Optometry which provides medical eyecare to underprivileged areas around the world. Averaging seven trips worldwide per year, one of the slated trips will be to Tanzania, east-Africa in December 2016.

With the assistance of the The Oregon Sight and Hearing Foundation(a project of the Lions Club) and many other groups which help to collect ‘old glasses’, students and doctors are able to examine & dispense glasses to those who would otherwise not have access to medical eye care and vision services.
This is an area of the world with great need, many of the nomadic people (the Maasai) have never seen a doctor of any sort in their lives. The amount of pathology & blindness in Tanzania is staggering. Ultraviolet light exposure is the leading cause of cataract formation, it can also contribute to macular degeneration and pterygium formation. These three causes of blindness could be reduced significantly by wearing non-prescription sunglasses.  |
