Summary

Purpose: Evaluation of one-year postoperative results after Supracor laser procedure.

Methods: The study group consisted of 8 hyperopic patients (16 eyes) seeking alternatives to wearing glasses for both distance and near vision. These patients underwent Supracor refractive surgery in the Department of Ophthalmology of The University Hospital Brno in the time period from July 2012 to February 2013. The patient mean age at operation was 57,2 years (±4,6), mean binocular uncorrected near visual acuity was Jaeger No. 13, distance visual acuity 0,5 (±0,19). Average follow-up period was 15,5 months (±2,4).We evaluated binocular uncorrected and best corrected distance visual acuity (UDVA, BCDVA), near visual acuity (UNVA, BCNVA), and intermediate visual acuity
(UIVA, BCIVA) 12 months after surgery, further the stability of visual acuity, objective refraction, mesopic contrast sensitivity, occurrence of complications, and patient satisfaction.

Results: In all 8 patients, binocular UDVA of at least 1,0 was achieved. The mean spherical equivalent was +0,25 D (±0,64). UNVA was Jaeger No. 3 or better in 7 patients (68,7 %), 5 of them could read Jaeger No. 1. UIVA Jaeger No. 1 was achieved in 5 patients (62,5 %), Jaeger No. 2 in 2 patients (25 %), and Jaeger No. 4 in 1 patient (12,5 %). In all eyes, preoperative mesopic contrast sensitivity was within the normal range for the given age. Postoperatively it remained within the normal range in 11 eyes (68,7 %). In 5 eyes (31,3 %) we found a decrease below the lower limit in higher spatial frequencies (12 and 18 cycles/degree) during the entire follow-up period. According to the patient questionnaire, 7 patients (87,5 %) were fully satisfied with the outcome of the surgery and they felt independent of wearing glasses, 1 patient was dissatisfied. 7 patients (87,5 %) did not report the presence of photic phenomena (halo, glare), 1 patient suffered from these problems.We did not encounter any intraoperative or postoperative complications.

Conlusion: According to our first experience, good distance, near, and intermediate visual acuity and a rather high patient satisfaction can be achieved with the use of the Supracor procedure. Supracor seems to be a suitable method of presbyopia correction in motivated, adaptable patients who meet strict indication criteria. With regard to the small number of patients in our study group, a greater number of patient evaluations will be required in the future, and long-term results will be of interest as well.

CONCLUSION Lymphangioma of the conjunctiva and rare observation of lymphangiomatosis cannot yet be influenced by complex therapy. Extraconal localisation of the tumour was successfully resolved through surgical intervention in two patients through total and subtotal resection respectively. For intraconal lymphangioma with generated neuropathy accompanied by CME a good choice was actinotherapy by linear accelerator, which enabled targeted focus on the tumour without side effects of radiation on the lens and other intraocular structures.
