This study reports the vision status of a presbyopic patient who has undergone a corneal inlay procedure. The study
hopes to provide optometrists more insight on the procedure and the co-management involved in such a patient. The
patient, a 48 years-old Chinese woman with presbyopia underwent the corneal inlay procedure three years ago.
She had the inlay implanted in the non-dominant eye to aid near vision i.e. her left eye. The pre and post-operative
evaluations include distance and near visual acuity, fundoscopy, tonometry, Schirmer’s test, slit lamp evaluation, corneal
topography and corneal pachymetry. Near visual acuity for the left eye improved from N14 to N5 immediately after
the procedure. Even after 3 years of post-operative followup, the patient was still able to maintain her near vision. In
conclusion, the corneal inlay procedure helped to improve near vision of this presbyopic patient. Optometrist plays
a very important role in the co-management of such patients alongside with the ophthalmologist in terms of visual
functional assessments pre and post-surgery, counseling of the procedure and managing patients’ expectations.

PURPOSE: This study analyzed the efficacy of Scion Image(R)program, the measurement of area of cornea lesion in the process of corneal diseases. METHODS: Photographs were processed digitally from three corneal wound lesions, and the Adobe Photoshop(R) and Scion Image(R) were used to calculate the area. These measured automatically the area of the damaged corneal lesion in numerical values, allowing precise calculation of the ratio of the wounded area to the entire cornea. RESULTS: In the first case of corneal abrasion by contact lenses, we were able to measure the ratio of the lesion, improving from 45% to 9% after two days of treatment. In the second case of the typical corneal ulcer, the infected area was 23.6% of the cornea before treatment, and decreased to 14.5% after treatment. In the third case of the ring shaped corneal ulcer, we were able to measure the lesion accurately using the Scion Image(R) CONCLUSIONS: The Scion Image(R)program may be used for the measurement of corneal surface lesion. It seemed to allow objective and accurate measurement.

3.Principles of Cataract Surgery.
Journal of the Korean Ophthalmological Society 1973;14(1):43-45
In surgical removal of cataractous lens the following principles should be kept in mind. (1) Remove the lens as completely as possible, without leaving the lens remnants in the pupillary area in order to achieve the best vision as possible. (2) Ocular tissues should suffer the minimum injury during the operation. This precaution can be applied especially to the corneal endothelium and the iris. (3) No derangement of the vitreous surface should occur. (4) Secure the corneo-scleral wound as tight as possible with care not to incarcerate lens tissues nor vitreous. Application of these principles to the individual cases was discussed.

PURPOSE: To report a case of infectious crystalline keratopathy caused by Alternaria in the corneal center. CASE SUMMARY: A 66-year-old male visited our clinic with right ocular pain and visual loss after corneal trauma caused by a foreign body hitting his right eye while performing farm work 1 month prior to his visit. The patient had no history of corneal surgery and long-term use of topical corticosteroid. A corneal epithelial defect and whitish snowflake margin infiltration around the corneal stroma were observed in the corneal center, but there was an absence of conjunctival injection and anterior segment inflammation. Cultures and a biopsy of the corneal scrapings revealed Alternaria species fungus. The patient was treated with 1% topical voriconazole and 0.5% moxifloxacin, together with oral voriconazole (400 mg/day). After 2 months of treatment, the disease was completely cured, with a minute corneal opacity. CONCLUSIONS: We successfully treated a rare case of infectious crystalline keratopathy caused by Alternaria, which has not been previously reported in the Republic of Korea.

5.Analysis of The Accouracy of The Keratometer and Computer Assisted Videokeratography in IOL Power Calculation.
Journal of the Korean Ophthalmological Society 1995;36(6):949-953
We used to measure keratometric readings for IOL calculation as obtained by keratometer (Javal ophthalmometer) and recently computer assisted videokerato graphy (C.V.K.). To compare with accuracy of two different instruments we analyzed 100 eyes using Javal ophthalmometer and 100 eyes using C.V.K. in phacoemulsification procedures. Postoperative two months later, we had conclusion which had no significant difference in predicted refraction between two groups and there are a little tendency in myopic pattern in C.V.K. group. Also we found less dioptric power difference between the two groups in younger age, male, irregular astigmatism and small wound.

Journal of the Korean Ophthalmological Society 1975;16(3):198-200
The effect of 1% atropine solution and 1% atropine ointment on healing of corneal epithelium in 20 rabbits was studied. Corneal epithelium was removed by #15 blade in central area of 7mm in diameter under topical anesthesia with 0.5% pontocaine. 1% atropine solution was applied three times daily to Rt. eyes, and 1% atropine ointment to Lt. eyes. Progress of epithelial healing was observed by fluorescent staining of the wound. At the end of 24 hours, fluorescent staining area was 46.90% in average for Rt. eyes, and 51.90% in average for Lt. eyes. At the end of 48 hours, it was 7.83% for Rt. eyes, and 11.0% for Lt. eyes. At the end of 72 hours, All of Rt. eyes did not stain, but 2 of 10 Lt. eyes were faintly stained. Difference between ophthalmic solution and ointment on the effect of corneal epithelial healing was not significant.

Journal of the Korean Ophthalmological Society 2017;58(5):503-508
PURPOSE: The purpose of this study is to evaluate the efficacy of the combined treatment of anterior stromal puncture with the concurrent use of 5% NaCl eye drops for 6 months for recurrent corneal erosion syndrome. METHODS: A retrospective chart review was conducted for 21 patients (21 eyes) who underwent the combined treatment of anterior stromal puncture with 5% NaCl eye drops qid for 6 months to treat recurrent corneal erosion syndromes. The patients' age, gender, history of corneal trauma, history of ocular surgery, recurrence rate, need for additional treatments after recurrence and complication were analyzed. RESULTS: The mean age was 42.05 ± 13.83 years (19-68 years) with no significant difference in gender, and the mean follow up period was 8.48 ± 2.76 months (6-15 months). Among the 21 eyes 14 eyes (66.7%) had a previous history of corneal trauma, 2 eyes (9.52%) had previous refractive surgery, 1 eye (4.8%) had corneal dystrophy, 2 eyes (9.5%) had diabetic mellitus and 5 eyes (28.81%) had an unknown origin. Furthermore, 3 eyes (14.3%) developed recurrences and 2 eyes were resolved with conservative treatment while 1 eye needed additional anterior stroma puncture. There was no recurrence after retreatment with anterior stroma puncture. No significant complications such as infection or inflammation developed with the exception of corneal opacity in which one patient developed glare due to corneal opacity. CONCLUSIONS: The combined treatment of anterior stromal puncture with 5% NaCl eye drops for a prolonged time might be effective at preventing the recurrence of refractory recurrent corneal erosion syndrome with conservative treatments.

Korean Journal of Ophthalmology 2001;15(2):94-97
We report the clinical features and the course of traumatic corneal endothelial rings by trauma. Fourteen eyes (of fourteen patients) with traumatic endothelial rings (twelve cases of BB shot injury), were enrolled in this study. With median follow-up interval of 50 weeks, initial and final best corrected visual acuity, presence of combined injuries such as gross hyphema, and time of disappearance of traumatic endothelial rings were recorded. And specular microscopic examination was performed. The duration of existence of traumatic endothelial rings was mean 4.6 days. On the specular microscopic examination, the count of corneal endothelial cells in the injured eye decreased by mean 16.8% (ranged from 1 to 56%) than that in the opposite unjnjured eye. The duration of existence of traumatic endothelial rings was 3.5 days in the group without combined angle recession and was 6.1 days in the group with combined angle recession. We suggest that the possibility of traumatic corneal endothelial rings and resultant endothelial cell loss and their clinical potential should be always kept in mind in ocular trauma, particularly BB shot injury.

9.A Case of Epithelial Downgrowth as a Complication of Penetrating Keratoplasty.
Journal of the Korean Ophthalmological Society 1978;19(1):75-79
Authors have experienced a case (aged 24, female) of epithelial downgrowth following partial penetrating keratoplasty. Clinically, this patient was received 7mm penetrating keratoplasty due to herpetic corneal Scar of right eye. After keratoplasty, iris prolapse through the wound dehiscence was occurred and then it was closed immediately with resection of prolapsed iris tissue. But, thereafter, the graft showed haziness which is suspected as a immune reaction and eventually the graft became irreversible opaque. A cosmetic epikeratoprosthesis waS attached on the opaque eye. But intractable secondary glaucoma was not controlled by medications. Finally the illed eye was enucleated and was confirmed histopathologically the main cause of graft failure which was presumed due to epithelial downgrowth into the anterior chamber.

10.A Clinical Study of Ocular Injuries.
Journal of the Korean Ophthalmological Society 1987;28(3):623-633
1,072 cases of ocular injuries, including 271 cases of in-patients, who visited department of ophthalmology of Chungnam National University Hospital from January 1,1981 to December 31, 1985, were clinically analyzed. The results were as follows: 1. The incidence of ocular injuries was 8.1% of all eye patients and 16.0% of all patients admitted to this ophthalmologic department. 2. The incidence was more common in male(82.0%) and in the age of 3rd to 4th decades(53.7%). 3. Monocular injuries accounted for 90.4% of ocular injuries. There was no significant difference in the incidence between the right and left eye. 4. Tho ocular injuries were more common in the spring(27.4%), but in children the incidence was higher during the vacation. 5. The patients who visited this hospital within 24 hours after injury accounted for 89.8%. 6. The most common cause of ocular injuries was fist or finger(15.9%), followed by iron products(12.6%) and traffic accident(10.9%), but the injuries by iron products(32.1%) were most common in the admitted patients. 7. The most common ocular injury was eyelid laceration (15.3%), followed by subconjunctival hemorrhage(12.5%) and conjunctival foreign body(8.6%). In the cases of in-patients, corneal laceration(21.2%) was most common, followed by corneoscleral laceration(14.9%) and lens perforation(10.2%). The corneal perforation was 52.1% of all perforating eye injuries. 8. Surgical procedure included corneal suture(21.1%), lensectomy(12.5%), enucleation or evisceration(11.2%), and others. 9. Visual acuity was improved in most cases by treatment, but the corrected vision after treatment was less than 0.1 in 33.2%, which was mainly due to the perforating eye injuries. 10. The most common complication of ocular injuries after treatment was corneal opacity(36.3%), followed by secondary glaucoma(14.6%) and traumatic cataract(6.4%).
