OBJECTIVE: To evaluate the therapeutic efficacy of suture-fixation of foldable intraocular lens for non-posterior-capsular aphakia. METHODS: Akreos intraocular lens (from Bausch-Lamb Company) were selected for operation in aphakia with non-posterior-capsule or less capsule supporting intraocular lens. Complications and visual acuity were observed. RESULTS: There was no significant complication in the operation. Choroidal detachment occurred in 2 eyes postoperatively. Visual acuity of 0.3 accounted for 56.67%, 76.67%, 86.67%, and 90% respectively on the first day, at 1 week, 1 month and 3 months after the operation. CONCLUSION Suture-fixation of Akreos intraocular lens is a good choice for non-posterior-capsular aphakia.

Perfluorocarbon liquids have been used to facilitate surgery in complicated retinal detachments or giant retinal tears which were difficult to manage. The results of perfluorophenanthrene usage in 26 eyes that had been taken vitreoretinal surgery were analyzed.The causes of retinal detachments were giant retinal tears in five eyes[19%], pseudophakia or aphakia in three[12%]and trauma in three.As tamponades, C3F8 gas was used in 11 eyes and silicone oil in 15 eyes. Overall, anatomical success rate was 73%and functional success rate was 58%.All of the giant retinal tears were successfully reattached and four eyes[80%]were functionally successful.The rates of anatomical success were 75%in eyes with grade C proliferative vitreoretinopathy, and 64%in grade D.Regarding postoperative tamponade materials, there was no significant difference between C3F8 gas and silicone oil.Releasing retinectomy was perfomed in four eyes and there was no functional success. In conclusion, perfluorocarbon liquid is a useful instrument that improves the result of operation of complicated retinal detachment if used selectively.

The accuracy of vision test chart is very important in examination of the visual acuity. The author examined the accuracy of the Cheongsan Vision Chart which is an imitative print of Dr. Chun Suk Hahn's Vision Test Chartby measuring it's test types of Landolt's rings, Arabic figures, Korean letters and pictures in detail with micrometer and surgical loupe. The errors in size of test types of Cheongsan Vision Chart to the standard size which was authorized by the Ministry of Health and Social Affairs of Korea in 1972 for the Chun Suk Hahn's Vision Test Chart are found as follows: 1. Error in Landolt's rings. 0.2-32.7%, av. 9.0%. Error over+/-10% in 35.7%. 2. Error in Arabic figures. 0.1-70.4% av. 12.8%. Error over+/-10% in 47.6%. 3. Error in Korean letters. 0.2-55.9% av. 15.4%. Error over+/-10% in 57.1%. 4. Error in pictures. 0.2-15.1% av. 0.9%. Error over+/-10% in 8.1%. In this study the author found that the Cheongsan Vision Chart is lacking in accuracy for examination of visual acuity.

Argon laser iridotomy was performed on 67 eyes, 49 patients with angle-closure glaucoma: 24 eyes(18 patients) with acute angle-closure glaucoma, 15 eyes(12 patients) with chronic angle-closure glaucoma, 4 eyes(4 patients) with pupillary block glaucoma in aphakia, 6 eyes(4 patients) with glaucoma to uveitis, and 18 fellow eyes on the patients who have monocular angle-closure glaucoma. Iridotomy holes were satisfactorily produced in every eye treated except one eye, 64 eyes(95.5%) having one or two treatment, but failed in one eye with acute type, The procedure was easily done with a small amount of laser energy when it used in the short duration of 0.05 second only rather than the long duration above 0.05 second or others. Postoperatively, of 38 eyes with primary angle-closure glaucoma treated successfully, 12 eyes(31.5%) required no medication, 21 eyes(55.3%) needed the addition of either one or two topical drugs, and filtering surgery was necessary in 5 eyes(13.2%). It was related to the extent of peripheral anterior synechiae. Other 26 eyes required no medication. The closure of iridotomy holes was rare and easily treated in two eyes with uveitic angle-closure glaucoma. And laser iridotomy revealed no major complication.

The trabeculectcmies were performed on 12 eyes with uncontrolled glaucoma which had not been treated by the maximum use of tolerated antiglaucoma medication. We assumed that all of these eyes would be at increased risk by episcleral cicatricial closure in the patient with one of the following cases; congenital glaucoma, age of 40 year or less, previously failed glaucoma filtration surgery, aphakia and uveitis. A standard operation was performed except tbat triamcinolone acetonide(4mg) was injected subconjunctivally at the intended trabeculectcmy site one week before surgery in 10 eyes, and cn the day of surgery in 2 eyes. During the followup period of 5 months or more, 11 of 12 eyes had an intraocular pressre(IOP) of 19mmHg or less. The average IOP for these 11 eyes was 14.5 +/- 3.4mmHg(mean +/- SD), and only 2 of the 11 eyes required antiglaucoma medication. One eye was a surgical failure. All eyes with controlled IOP showed micro cystic filtration blebs on slit lamp examination. The postoperative visual acuity was within one line of the preoperative level in all eyes, except for the one surgical failure. The use of triamcinolone acetonide does not seem to have added any additional risks to the postoperative period.

In this case series, we assessed a new technique, the intrascleral pocket procedure of transscleral fixation (TF) of the intraocular lens (IOL) in post-vitrectomized eyes. We performed the transscleral fixation of IOL in four aphakic patients who underwent pars plana vitrectomy. Two points 180degrees apart were marked at the limbus. A 2-mm-sized intrascleral pocket was created by lamellar dissection using a crescent blade without conjunctival dissection. A 2.8-mm clear corneal incision (CCI) was made using a keratome. Prolene sutures were exteriorized through the CCI pocket and a three-piece foldable acrylic IOL was injected via CCI and the ends of the haptics were exteriorized through the CCI. The prolene sutures for each haptic in the intrascleral pocket bed were then tied and knots were buried under scleral flaps. No patient had complaints such as conjunctival irritation, and visual acuity was almost identical to preoperative best-corrected visual acuity at day 1 postoperatively. IOLs were well placed without tilting or subluxation. They had no wound dehiscence or endophthalmitis postoperatively. The intrascleral pocket procedure of TF without the need for conjunctival dissection is a successful method for sulcus fixation in post-vitrectomized eyes predisposed to developing glaucoma.

OBJECTIVETo evaluate the therapeutic effect of laser photocoagulation of ciliary processes after pars plana vitrectomy in aphakic glaucoma.

METHODSTwenty patients (20 eyes) of aphakic glaucoma underwent vitrectomy plus laser treatment. During the surgery, after conventional 3-incision pars plana vitrectomy, a probe of semi-conductor diode laser (532 nm) was inserted through the sclera incision, the ciliary processes were then photocoagulated under direct visualization for 180 degree range. Before and after the surgery, the visual acuity, the intraocular pressure (IOP) as well as the outer appearance of the anterior segment were evaluated. The mean follow-up period was 13 months.

RESULTSThe IOP at the last visit was (21.35 +/-2.52) mmHg, which was significantly lower than that before the surgery [(39.75 +/-6.27) mmHg, P=0.000]. Atrophy of the ciliary processes was observed 1-3 months after the surgery.

CONCLUSIONPars plana vitrectomy combined with laser coagulation of ciliary processes reduces the IOP in patients with aphakic glaucoma effectively.

Aphakic or pseudophakic glau-oma is known to be at high risk for failure after filtration surgery. The authors retrospectively investigated the results of trabeculectomy in 14 eyes of 14 patients with glaucoma, seven aphakic and seven pseudophakic eyes, which were followed from six months to three years with an average ot 16.5 months. A conventional trabeculectomy without using antifibrotic agents was performed in all the eyes. The site of conjunctival incision was prepared on the virgin area of the conjunctiva; 8 superonasal, 4 inferonasal and 2 inferotemporal approaches. An average postoperative intraocular pressure reduction was 13.4 mmHg. The number of medications decreased in 11 eyes. A spontaneously developed functioning bleb was found in seven eyes. In other four eyes, the filtering bleb was formed with an aid of massage or needling. The remallllllg three eyes did not show a functioning bleb. Postoperative complications included hyphema in 3 eyes, overfiltration in 2 eyes, choroidal detachment in 1 eye, corneal edema in 1 eye and endophthalmitis in 1 eye.

We retrospectively evaluated the clinical characteristics and surgical outcomes of 20 pseudophakic retinal detachment (RD) patients (20 eyes) and 17 aphakic RD patients (17 eyes). Males were predominated in both groups. The time interval between cataract extraction and RD was 31 months on average in the pseudophakic group, 32 months with intact posterior capsule and 27 months with ruptured posterior capsule, and 148 months in the aphakic group. In 50% of cases with ruptured posterior capsule in the pseudophakic group, RD occurred within 1 year. The anatomic success rate was 95% in the pseudophakic group and 88% in the aphakic group. The most common cause of failure was the development of proliferative vitreoretinopathy. Visual acuities more than 20/40 after RD surgery were found in 13 pseudophakic (65%) and 6 aphakic (36%) eyes. Aphakic patients were more inclined to have silent RD than pseudophakic patients because of their poor visual acuity. Post-operative follow-up is required especially for the first 1 year in cases of damaged posterior capsule due to the high incidence of RD during this period.
