This study comprised 9 eyes with severe myopia of 7 patients (4 male, 3 female) between 36 and 50 years, having phacoemulsification, intraocular lens implantation with suitable capacity. Follow up duration was 12 months. Results: the preoperative uncorrected visual acuity was < 1/10 in all patients. Postoperatively, 55.5% cases with uncorrected visual acuity and 66.7% cases achieved the best corrected visual acuity of 5/10 or better. The mean preoperative hyperopic spherical equivalent was +6,89 ± 1,67D reduced to +0,75±0,62D. Postoperative complications were low: 1 eye had posterior capsule opaque (11,1%), 1 eye had inflammatory membrane. No intraoperative complications

PURPOSE: To evaluate the effects of occlusion therapy on anisometropic amblyopia and investigate the factors that influence on the final vision. METHODS: Fifty two patients with anisometropic amblyopia, whose age ranged from 3 to 12 years, were treated with full and partial occlusion therapy. RESULTS: The degree of anisometropia was 3.23+/-1.99 D in hyperopia group and 2.00+/-0.98 D in myopia group. The best corrected visual acuity and final vision were 0.29+/-0.14 and 0.52+/-0.22 in hyperopia group, while 0.34+/-0.16 and 0.63+/-0.16 in myopia group. But statistically significant difference was not found between two groups. The best corrected visual acuity was significantly correlated with the degree of anisometropia. The final vision was also significantly correlated with the degree of anisometropia. As expected, the final visual acuity was strongly correlated with the best corrected visual acuity. But no statistically differences were found based on the age of initial treatment and sexual difference. CONCLUSIONS: The severity of amblyopia and the effect of occlusion therapy were more correlated with the degree of anisometropia than the age of initial treatment and the type of anisometropia.

PURPOSE: To investigate bilateral medial rectus recession by considering functional equator as a surgical guideline in esotropia over 40 prism diopters (PD). METHODS: Forty-one patients who underwent bilateral medial rectus recession, and were followed-up for more than 12 months, were reviewed. The success rate was compared between group 1 and group 2, which were divided to recession site from the functional equator posterior, and also between the hyperopia group and myopia group according to refraction. RESULTS: According to preoperative deviation angle, 21 patients underwent recession to less than 10 mm posterior to the functional equator (group 1) and 20 patients had recession to 1.5 mm to 2.0 mm posterior to the functional equator (group 2). No significant difference in success rate between group 1 (71.4%) and group 2 (75.0%) was detected at the last follow-up. When divided into a hyperopia group (26 patients) and myopia group (15 patients), the success rate in the myopia group was higher than in the hyperopia group, as observed at the last follow-up, but the difference was not significant. There was 1 case of overcorrection in each group. CONCLUSIONS: A successful outcome was achieved in 30 patients (73.2%), and overcorrection in 2 patients (4.9%) when recessed to 2.0 mm posterior to functional posterior in esotropia over 40PD.

Cycloplegic refraction with 1% cyclopentolate and I % atropine was performed in esotropic children younger than 6 years. The purpose of this study was to find clinical factors related with differencs in refractive changes between cyclopentolate and atropine Additionally, the periodic refractive changes at the first, second and third day during performing traditional atropinization were evaluated. The results were as follows: The refractive state after using 1 % cyclopentolate was + 5.00 diopters in average and that after using 1% atropine was +5.77 diopters in average (phyperopia more than +4.00 diopters and young age less than 4 years but AC/A ratio was not related. The periodic refractive changes at the first, second, and third day during atropinization were statistically significant.

PURPOSE: This study examined differences in clinical patterns according to the hyperopia level in refractive-accommodative esotropia patients. METHODS: Ninety-four refractive-accommodative esotropia patients were divided into 3 groups according to hyperopia level: group 1, > or = +1.00D and < +3.00D group 2, > or = +3.00D and < +5.00D and group 3, > or = +5.00D. The following factors were analyzed retrospectively: the initial corrective visual acuity, the final corrective visual acuity, the angle of esotropia with or without hyperopic correction, the recovery time to orthophoria after hyperopic correction, the change in hyperopia level, and the frequency of amblyopia. RESULTS: The angles of esotropia without hyperopic correction in groups 1, 2 and 3 were 18.4+/-7.3PD, 22.9+/-8.5PD, and 25.7+/-10.4PD, respectively. The angle of esotropia was found to be significantly greater in the group with the higher level of hyperopia (P=0.01). The monthly change in hyperopia in groups 1, 2 and 3 was 0.018+/-0.02D, 0.028+/-0.03D and 0.043+/-0.03D. The change was greater in the group with the higher level of hyperopia (P=0.009). CONCLUSIONS: In refractive-accommodative esotropia patients, the more the hyperopia without correction increases, the more the angle of esotropia without correction increases, and the larger the reduction of hyperopia after correction becomes.

PURPOSE: To evaluate clinical effects of laser thermal keratoplasty (LTK), LTK was performed in patients with presbyopia or hyperopia. METHODS: LTK was performed in 38 patients who was older than 45 between May and December 2001. Preoperative contact lens fitting and wearing for patients to experience the monovision was tried in all patients for one week. With LTK, we intended patients used dominant eyes for distance vision and nondominant eyes for near vision. Patients' satisfaction, refractive change and near visual acuity were evaluated for least 3 months after surgery. RESULTS: The mean improvement of near vision was 5.16 lines by test with Korean near vision chart. 79% (30 of 38) of patients were satisfied with the results of LTK. CONCLUSIONS: Monovision with LTK is thought to be a good option in patients with presbyopia.

We reviewed records of 50 bilateral hyperopic amblyoic patients who visited ophthalmologic clinic at Yeungnam University Hospital between December 1984 and October 1993, and investigated the effect of age at initial correction, magnitude of hyperopia and duration of correction on corrected visual acuity with the lapse of time. Criteria for selection included the followings; hyperopia of 3.50 diopters or more, astigmatism of 2.50 diopters or less, and anisoametropia of 1.25 diopters or less. Full cycloplegic corrections were prescribed at the initial visit to all subjects. The distribution of initial corrected visual acuity was 0.1 to 0.5. Age at initial correction varied from 2 years to 8 years(mean 3.98 years). The magnitude of hyperopia appeared to have the greatest influence on the visual outcome at initial correction. Duration of correction also influenced on the visual outcome, showing continuous visual improvement during 4 years after initial correction. The age at initial correction did not appear to influence on the initial and final corrected visual acuity. A comparision between initial and final corrected visual acuity showed a sigificant difference, irrespective of age at the intial correction or magnitude of hyperopia.

Distributions of angle kappa and of cycloplegic refraction and their association were studied. The subjects were 282 nonstrabismic Korean children, aged from 6 years to 11 years. who visited Ewha Women University Hospital from December 1990 to March 1991. The angle kappa was measured by major amblyoscope, and refraction was done under the cycloplegic state. The results were as follows: The frequency of angle kappa was positive. negative and 0 degree in decreasing order. The average values of refractive error and angle kappa were -1.03 +/- 2.20 degrees dipter and +1 34 +/- 1.33 degrees. The average values of angle kappa for hypermetropia, emmettopia and myopia were +2.52 +/- 0.81 degrees, +1.71 +/- 1.03 degrees and +0.90 +/- 1.37 degrees. And these values were significantly different from each other.

Orthokeratology is the way to correct the myopia or astigmatism by flattening or the central cornea with specialty lenses. The range of correction is from − 2.50 to − 4.00 diopters after 10 days of fitting. The designs is constructed with flat base curve radius, steep reverse curve, flat alignment curve, and peripheral curve. This multi-cuve design enabled the orthokeratology lenses to stay on the cornea stably and effectively. Recently, the application of orthokeratology is extending to hyperopia and presbyopia. In the future, the amount of correction and the application of orthokeratology will increase more and more.
