[Correction of the astigmatism with the Artisan phakic toric lens].

The implantation of the intraocular anterior chamber phakic toric lens (PTIOL) Artisan, a product of the Ophtec company, is one of the most up-to-date methods of the correction of higher degree of myopic as well as hyperopic astigmatism. The authors refer about the results of PTIOL Artisan implantation in 6 patients (10 eyes). The major indication was the hyperopic astigmatism--in 5 patients (8 eyes); in one patient the indication was myopic astigmatism. In the followed up group of patients, there is the preponderance of men (5), and one woman only. The patients were divided into two subgroups: one with myopic astigmatism (1 patient, 2 eyes) and other with hyperopic astigmatism (5 patients, 8 eyes). The average age of the whole group at the time of the surgery was 27.7 +/- 2.8 years (range 23-38 years) and the average follow up period was 13.0 +/- 6.9 months (range 6-22 months). In the group the patients with follow up period shorter than 6 months were not included. The average preoperative spherical refractive error was +4.8 +/- 2.25 dioptres (D) and the average astigmatic error was -5.15 +/- 2.82 cylinders (Dcyl). In one case of myopia, the preoperative refractive error in both eyes was -7.0 D and -3.5 Dcyl. The target refraction was emetropia +/- 1.0 D. The authors evaluate the final uncorrected and best-corrected visual acuity (UCVA, BCVA), final postoperative refractive error, presence of intra- as well as postoperative complications, and changes of endothelial cells' density over time. The average final postoperative error in patients with hyperopic astigmatism was +0.72 +/- 0.93 D and -1.08 +/- 0.60 Dcyl. In the only patient with myopic astigmatism the final postoperative error of both eyes was +0.5 D and -0.5 Dcyl. The advantage of the PTIOL implantation is fast visual recovery, potential reversibility of the procedure, maintaining of the accommodation, and stability of the postoperative refraction.

[The use of accommodative lenses for surgical correction of the presbyopia using the Prelex method].

The authors refer about their experience with the surgical correction of the presbyopia by means of the Prelex (presbyopic lens exchange) method. Patients, who underwent this type of refractive surgery procedure to decrease their dependency on glasses correction for far as well as for near vision (12 patients, 23 eyes) and 1 young female patient (2 eyes) with juvenile cataract and high hyperopia, were included in the study. The average age at the time of the surgery was 51.0 +/- 5.5 years (range, 19-77 years). The average follow up period of the whole group of patients is 9.8 months (range, 1-13 months). Depending on the type of the lens implanted, the group was divided into subgroup A with the accommodative lens 1 CU produced by Human Optics Company implanted, and subgroup B with the accommodative lens Kellan TetraFlex KH 3500 produced by LensTec Company implanted. The subgroup A consists of 8 patients (15 eyes) with the average preoperative refractive error +2.35 +/- 3.45 diopters. The average uncorrected visual acuity of this group was 0.24 +/- 0.18, and the average best-corrected visual acuity was 0.77 +/- 0.22 at the time before the surgery. The average glasses correction for near was +4.1 dioptres, and the uncorrected vision for near was Jaeger's table Nr. (J) 13. The B subgroup consists of 5 patients (10 eyes). The average preoperative refractive error was +2.23 +/- 0.93 diopters. The average value of the uncorrected visual acuity before the surgery was 0.43 +/- 0.28, and the average corrected visual acuity was 0.82 +/- 0.25. The average value of the glasses correction for near was +5.25 and uncorrected vision for near J 13. The final average postoperative error at the time of the last visit was in the A subgroup +0.06 +/- 1.17 dioptres. The average uncorrected visual acuity was 0.69 +/- 0.24, and the average best-corrected visual acuity 0.96 +/- 0.12. The average vision of the patients of this subgroup for near was J 3. In the B subgroup we found at the last visit the average final value of the postoperative refractive error -0.2 +/- 0.72 dioptres. The average uncorrected visual acuity 0.57 +/- 0.22 and the average corrected visual acuity 0.95 +/- 0.12. Average uncorrected vision for near was J 5. We did not notice any serious per- or postoperative complication of this procedure.

[Specific chorioretinitis--a case report].

The authors present an uncommon case of ocular involvement in extrapulmonary form of tuberculosis with cutaneous manifestation. A case of a patient who was treated for skin efflorescences on legs for several months is demonstrated. The eye examination showed the picture of chorioretinitis of suspicious tuberculous etiology. A prompt healing of cutaneous lesions occurred and retinal finding stabilized under the specific therapy. The authors emphasize that this infectious etiology should not be omitted in differential diagnostic considerations of uveitis.

[Implantation of multifocal intraocular lenses].

The authors refer to the first experience in implantation of multifocal intraocular lens (MIOL) AMO ARRAY (model SA 40 N) produced by Allergan to a group of 35 patients (69 eyes). The proportion of men in the group was 42.9%, women being 57.1%. The mean age of the group was 50.9 +/- 4.3 year, range 36-71 years. The implantation of this type of intraocular lens was made due to a refractory intervention on a clear lens in 84.0% eyes and operation on cataract in 16.0%. The study was aimed at evaluation of the results of visual acuity for short and long distances, resulting refraction after the operation, the occurrence of side visual phenomena and their tolerance by the patient, necessary supplementary eyeglass correction especially in patients after refraction lensectomy. Uncorrected visual acuity for long distances 0.7 or better was in 75.9% of patients. Sixty one % of patients with MIOL in both eyes do not require glasses for vision into short distances (No 1-3).

[Photorefractive keratectomy in hypermetropia].

AIM: To evaluate the results in patients with hypermetropia having undergone photoreactive keratectomy (PRK). GROUP AND METHODS: The authors present a retrospective analysis of the results in 40 eyes operated on PRK in the period of September 1997 to November 2002 at the Eye Clinic of the Faculty Hospital in Hradec Králové. The mean preoperation spherical refraction was 2.90 +/- 0.98 dioptry (D), the mean astigmatism being -0.82 +/- 0.78 D, visual uncorrected visual acuity (NZO) 0.37 +/- 0.37, the mean corrected visual acuity (KZO) 1.28 +/- 0.27). RESULTS: One year after the operation on 31 eyes, the resulting mean spherical refraction was 0.76 +/- 1.10 D, the mean astigmatism being -1.01 +/- 0.80 D, NZO 0.77 +/- 0.18, KZO 0.99 +/- 0.21, NZO 6/12 and better was detected in 94% of surgically treated eyes. CONCLUSION: The PRK method has been found sufficiently effective for the correction of low and medium hypermetropia.

[Posterior scleritis--a case report].

Authors present clinical manifestation and therapeutic possibilities in posterior scleritis, a disease, which may cause diagnostic dilemma. They also give an account of new examination methods which amend the diagnostic schema and safely confirm this diagnosis. In the article, a disease of a seventeen years old man is presented, in which posterior scleritis of unknown etiology was diagnosed. Following the systemic corticosteroid treatment the visual acuity of the affected eye improved, subjective signs disappeared, and the clinical manifestation returned to normal.

[Refractive surgery in myopia up to -6D].

OBJECTIVE: To evaluate the clinical results in patients with myopia up to -6 dioptres (D) after refraction surgery, evaluate their stability and compare photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). MATERIAL AND METHODS: The authors evaluated before and after surgery the refraction values in patients with myopia up to -6 D operated in 1999 and 2000. The patients were subjected to standard examination before operation, one week, 1, 3, 6 and 12 months after operation. The group comprised a total of 542 eyes, 452 PRK eyes and 90 LASIK eyes. RESULTS: After PRK surgery the mean spherical refraction after one year was -0.35 +/- 0.71 D, the mean astigmatism -0.63 +/- 0.38 D, UCVA 0.90 +/- 0.19, BCVA 0.98 +/- 0.11. After LASIK surgery after one year the mean spherical refraction was -0.10 +/- 0.81. D, the mean astigmatism -1.05 +/- 0.65 D, UCVA 0.80 +/- 0.24, BCVA 0.86 +/- 0.21. CONCLUSION: Both methods proved effective and safe for correction of myopia up to -6 D. The results at our clinic are comparable with other departments and are stable in different years. PRK and LASIK achieve equal postoperative results after an interval of 3 to 6 months following surgery.

[Long-term results of photorefractive keratectomy in myopia up to -6 D].

OBJECTIVE: To present clinical results of patients with myopia up to -6 dioptres (D) after photorefractive keratectomy (PRK) and evaluate their stability during a 4-year period. MATERIAL AND METHODS: The authors evaluated retrospectively the refraction before and after surgery in patients with myopia up to -6 D during the period from September 1997 till December 2000. The group comprised a total of 847 eyes. The mean spherical refraction during the whole follow up period was before surgery -3.61 +/- 1.17 D, the mean astigmatism was -0.65 +/- 0.63 D, non-corrected visual acuity (UCVA) 0.09 +/- 0.09, the visual acuity with optimal correction (BCVA) 1.21 +/- 0.30. RESULTS: One year after PRK we achieved in our group a mean spherical refraction of -0.17 +/- 0.74 D, a mean astigmatism of -0.61 +/- 0.43 D, UCVA 0.92 +/- 0.25, BCVA 1.02 +/- 0.19. CONCLUSION: Photorefractive keratectomy is an effective and safe method for correction of myopia up to -6 D. The results as regards refraction were comparable with other departments and did not differ much during individual years. Stabilization occurs 3-6 months after the operation.

[Visual function in high myopia corrected with anterior chamber phakic lens (PK PIOL). Initial results].

20 eyes (12 women, 8 men) undergoing implantation of anterior chamber phakic IOL (PIOL) for correction of the refractive error were examined before and 1 and 6 months after surgery. Median of preoperative spherical equivalent of refraction was -9.75 D (range -19.00 to -6.00 D). Contrast sensitivity (CS) was tested on a computerized system of the Contrast sensitivity 8010 type in 6 spatial frequencies (range 0.74 to 29.55 c/deg) and using the Ginsburg's charts also in 6 spatial frequencies (range 1.15 to 27.25 c/deg), the best corrected visual acuity (BCVA) was measured on the normalized charts with Landolt rings, influence of glare of 342 cd/m2 was examined using Brightness Acuity Tester. At 6 months postoperatively, median of spherical equivalent of refraction was 0.00 (-1.00 to 0.00). BCVA increased from 0.79 (range 0.50 to 0.97) preoperatively onto 0.96 (range 0.83 to 1.00). Median of CS increased in all spatial frequencies tested using both methods, significantly in the middle and high frequencies and CS almost, reached lower border of CS normal range. Glare had only nonsignificant influence on both BCVA and CS. Quality of vision postoperatively improved significantly.

[Comparison of visual function in myopia over -6.0 dpt after photorefractive keratectomy and laser in situ keratomileusis].

1. 41 myopes undergoing PRK and 31 patients undergoing LASIK for correction of spherical refractive error were examined before and 1, 3, 6 a 12 months after surgery on Schwind Multiscan with ablation zone between 5 and 7 mm. Mean preoperative spherical equivalent of refraction was -8.0 +/- 1.7 D in PRK group and -9.2 +/- 2.1 D in LASIK one. 2. Contrast sensitivity (CS) was tested on a computerized system of the Contrast sensitivity 8010 type in 6 spatial frequencies (0.74; 1.97; 3.69; 7.39; 14.77; 29.55 c/deg) and the best corrected visual acuity (BCVA) was measured on the normalized charts with Landolt rings. 3. At 12 months postoperatively, mean spherical equivalent of refraction was -0.6 +/- 1.0 D (PRK) and -1.0 +/- 0.8 D (LASIK). A refractive error within +/- 0.5 D had 31.5% (PRK) and 57.5% (LASIK) patients. Increasing of BCVA was measured in 51.5% (PRK) and 41.9% (LASIK) patients about 1 optotype to 2.5 lines. Mean CS in 6 frequencies reached 99.4; 102; 105; 109; 115 and 140% of preoperative values in PRK group and only 96; 95.8; 96.3; 95.8; 97.8 and 94.6% in LASIK one. 4. At 12 months after surgery, mean spherical equivalent, CS was better and number of patients with increased BCVA was significantly higher after PRK, than those attained with LASIK. On the other hand, a number of patients with a refractive error within +/- 0.5 D was higher and percentage of reoperations was lower in LASIK group.

[PRK and LASIK in patients with myopia ranging from -6 to -9 D] ].

OBJECTIVE: Observing of effectiveness, safety and short-term stability of patients with myopia ranging from -6.0 to -9.0 diopters (D) after surgery and their comparison. PARTICIPANTS AND METHOD: We were retrospectively analyzing pre- and postoperative outcomes of patients with myopia ranging from -6.0 to -9.0 D. 90 eyes were examined before laser in situ keratomileusis (LASIK) with mean spherical equivalent refraction -7.64 +/- 0.84 D and mean cylinder -1.23 +/- 1.1 D. 56 eyes were examined before photorefractive keratectomy (PRK) with mean spherical equivalent refraction -6.92 +/- 0.72 D and mean cylinder -0.60 +/- 0.55 D. Patients were examined before operation, one week, one month, three months, six months, nine months and one year after operation. Data were collected and analyzed by the computer programme. RESULTS: We observed the patients who underwent the operation and six months after surgery we received following results: After PRK mean spherical equivalent refraction was -0.23 +/- 1.24 D, mean cylinder -0.83 +/- 0.42 D, uncorrected visual acuity (UCVA) 0.86 +/- 0.35, best spectacle-corrected visual acuity (BCVA) 1.13 +/- 0.33. After LASIK mean spherical equivalent refraction was -0.29 +/- 1.19 D, mean cylinder -1.14 +/- 0.77 D, UCVA 0.65 +/- 0.25, BCVA 0.83 +/- 0.25. One year after PRK mean spherical equivalent refraction was -0.44 +/- 1.26 D, mean cylinder -0.80 +/- 0.57 D, UCVA 0.81 +/- 0.31, BCVA 0.97 +/- 0.21. After LASIK mean spherical equivalent refraction was -0.14 +/- 0.86 D, mean cylinder -1.26 +/- 0.89 D, UCVA 0.75 +/- 0.25, BCVA 0.89 +/- 0.20. CONCLUSIONS: Both methods are effective and their results after 3 to 6 months after laser treatment in patients with myopia ranging from -6.0 to -9.0 D were comparable. Based on the complex evaluation, we prefer LASIK nowadays.

Retreatment after photorefractive keratectomy for low myopia.

OBJECTIVE: The purpose of the study was to evaluate the results of retreatment for low myopia after primary photorefractive keratectomy (PRK). DESIGN: A prospective study. PARTICIPANTS: A total of 48 eyes of 37 patients from 566 eyes of 331 patients originally treated for myopia of up to -6 diopters (D) were studied. INTERVENTION: Photorefractive keratectomy by the Coherent Schwind Keratom II excimer laser was performed. MAIN OUTCOME MEASURES: The parameters evaluated were visual acuity, refraction, and corneal clarity. RESULTS: Of the 566 eyes with myopia up to -6 D, 48 eyes (8.5%) required retreatment. The sphere (mean +/- standard deviation) was -0.88 +/- 1.24 D before second surgery. At 6 months, the mean was -0.04 +/- 0.91; at 1 year, it was -0.33 +/- 0.75 D. At 6 months, 75% of sphere value was within +/- 1 D. The preoperative uncorrected visual acuity (UCVA) was 20/200 or worse in 12.8% of eyes and 20/40 or better in 40.4% of eyes. Six months after reoperation, 20/60 UCVA was obtained in 17.4% of eyes. All others (82.6%) had UCVA of 20/40 or better, 26.1% better than 20/20. The proportion of eyes with best spectacle-corrected visual acuity better than 20/20 decreased from 60.0% to 47.1% 6 months after reoperation. Six months after reoperation, haze 1 was present in 42.9% and haze 2 in 4.7% of eyes, and in no eye was haze worse. CONCLUSION: Retreatment after PRK for low myopia can significantly increase UCVA and decrease residual refractive error without significant complications.
