Scleral Contact Lens Usage in Patients With Complex Blepharoptosis

Abstract

To evaluate the efficacy of scleral contact lenses (ScCLs) as an alternative or as an adjunct to surgical correction for the management of complex ptosis. A retrospective case-note review was used to determine the subjective function and cosmetic acceptability of the lenses. Digital photographs were taken, both with and without the lens in place; analytic software was used to assess the vertical height of the palpebral aperture (PA) and the upper margin-reflex distance. Three masked observers independently graded the photographs for cosmesis as "good," "moderate," or "poor." Ten patients (6 male) had been wearing ScCLs in 14 treated eyes for between 1 and 40 years (mean, 10.3 years; median, 3 years). Without a lens, the mean PA was 4.9 mm (median, 5.1 mm; range, 1.7-7.1 mm), increasing to 9.5 mm (median, 8.9 mm; range, 5.8-14.8 mm) with the lens in place (p < 0.005). Likewise, the upper margin-reflex distance increased from 0.39 mm (median, 0.03 mm; range, 0-2.4 mm) without a lens in place to 3.1 mm (median, 2.7 mm; range, 1.5-5.8 mm) with lens wear (p < 0.005). In 6 patients with unilateral ScCL wear, mean PA was 10.4 mm in the treated eye and 8.4 mm in the eye without a lens (p = 0.22). All patients who were wearing ScCLs long term found them to be both comfortable and cosmetically acceptable. On subjective grading of photographs, however, the cosmesis was judged as "good" in 22%, "moderate" in 64%, and "poor" in 14%. In some patients, ScCLs provide a well-tolerated and practical long-term solution to safely elevating the upper eyelid in which complex ptosis is present. The patients in our cohort seem to be satisfied with the cosmesis, although there are some limitations to this aspect when viewed subjectively.
