The study involved 57 patients (61 eyes), including 32 males and 25 females who underwent intra- or extra-capsular lens removal and who were candidates for artificial lens placement. The result showed that artificial lens can be placed by one of two ways: placed in anterior chamber or trans-scleral suture fixation of artificial lens for eyes where the posterior capsule is absent or ruptured. Postoperative outcomes are encouraging. At 6 months after operation, the vision is less than 0.1 in 24 eyes; between 0.1 to 0.4 in 32 eyes; more than 0.05 in 4 eyes and one eye have unmeasurable vision. At 3 months after operation, intraocular pressure is less than 25 mmHg in 28 eyes and more than 25 mmHg in 3 eyes.

17 cases of luxation and subluxation of the lens due to the acute uveitis received an operation for removal of lens and implantation of the artificial lens in the posterior chamber and fixation of it in the sclera during 1993-1997. The monitoring duration was 3 years. The results of anatomy and tolerance were good. The rate of patients with vision improvement after 3 years of operation was 100% in which 57.14% of patient had vision ability of 0.1-0.6. This depended mainly on the treatment of visual insufficiency after operation.

Objective: To determine refractive changes in children post-cataract extraction and intraocular lens (IOL) implantation at a Philippine tertiary hospital. Methods: This is a retrospective cohort study involving patients aged 1 to 10 years in the Department of Ophthalmology of a Philippine tertiary hospital who underwent cataract extraction and IOL implantation between 2004 to 2013. Results: We included 55 eyes of 34 patients in the analysis. Thirty-eight eyes (69%) eyes underwent primary IOL implantation. The mean duration of follow-up was 3.5 ± 2.1 years. The median refractive changes were -2.00 (-2.50, -0.50) diopters (D) for the 1- to 3-year-old group, -1.25 (-1.50, -0.25) D for the 4- to 7-year-old group, and -1.00 (-1.63, -0.25) D for the 8- to 10-year-old group. Only the 1- to 3-year-old group had significant difference between the initial post-operative refraction and the latest follow-up refraction (p<0.001). For the primary implantation group, patients in the 1- to 3-year-old group had the highest median refractive change at -2.00 (-3.125, -1.00) D while patients in the 8- to 10-year-old group had the highest median refractive change at -2.12 (-2.56, -1.69) D in the secondary implantation group. Refractions of eyes with IOL-implanted and normal eyes showed a median difference of -1.00 (-0.25, -3.5) D. Conclusion The determination of the power of IOL implants in pediatric patients who underwent cataract extraction remains challenging despite availability of recommendations.

Electroretinogram(ERG), widely used to diagnose and prognose the retinal dysfunctions, is known to be affected by the various testing conditions, such as the amount and color of the stimulating light, adaptation time and background light intensity. We have recorded the ERG in 39 cataract patients(50 eyes)without retinal abnormalities in order to evaluate the effect of intraocular lens(IOL)on the ERG and to compare clear-IOL inserted eye with colored-IOL inserted eye. The insulting effect of IOL material did not affect the results of the ERG. However the rod response in IOL inserted eye showed shortening in implicit time, which was probably due to the increase of inputting light by the removal of opaque lens. Additionally, there was no difference between the ERG of colored-IOL(yellow-tinted IOL)eyes and that of clear-IOL eyes. We found that ERG might be used in the IOL inserted eyes without modification of data values.

PURPOSE: We compared the clinical results after implantation of the newly-developed aspheric intraocular lens iSert 250 NC60 (Hoya Corporation Ltd., Tokyo, Japan) with 2 other types of widely used intraocular lenses, AcrySof IQ SN60WF (Alcon Laboratories, INC., Fort Worth, TX, USA) and TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana, CA, USA). METHODS: Seventy cataract eyes were implanted with 1 of 3 aspheric intraocular lenses (Hoya iSert 250 NC60, TECNIS 1-piece ZCB00 or AcrySof IQ SN60WF) by the same surgeon. Uncorrected vision, best corrected vision, spherical equivalent, higher order aberrations, and modulation transfer function were measured 1 and 3 months after the cataract surgery. RESULTS: Uncorrected vision and best corrected vision were not significantly different among the 3 groups; however, eyes implanted with iSert250 NC60 showed more hyperopic-shifted postoperative spherical equivalents than expected compared to the other 2 groups. Total ocular aberrations and internal optics aberrations were similar among the 3 groups while the root mean square of the corneal aberrations showed differences. Eyes implanted with iSert 250 NC60 showed superior results in modulation transfer function compared with the other 2 groups in a majority of spatial frequencies 3 months postoperatively. CONCLUSIONS: The newly developed aspheric intraocular lens iSert 250 NC60 showed clinically equal results compared with 2 other verified intraocular lenses AcrySof IQ SN60WF and TECNIS 1-piece ZCB00 in vision, higher-order aberrations, and modulation transfer functions.

We analysed postoperative corneal astigmatic changes to know that preoperative astigmatism was able to decreased according to the location of incision in sutureless cataract surgeries. We divided 70 patients, 81 eyes that scleral pocket incision, phacoemulsification, and posterior chamber intraocular lens implantation was performed into two groups. The one is the preoperative with-the-rule(WTR)astigmatism more than 1 diopter(D) with superior incision, and the other is the preoperative WTR less than 1D or against-the-rule (ATR) astigmatism with temporal incision. We followed up the corneal astigmatic chnges until six months postoperatively. According to the results of algebraic analysis, in the superior incision group, postoperative astigmatic changes showed WTR decrease of 0.43D immediately, which advanced toward ATR decrease of 0.41D immediately, which keep up ATR decrease and showed ATR decrease of 0.44D at 6 months. According to the results of vector analysis, surgical inducced corneal astigmatism was o.69D in superior incision group and 0.50D in temporal incision group at postoperative 1day. It was 0.98D in superior incision group and 0.57D in temporal incision group at postoperative 6 months. We could decrease preoperative corneal astigmatism with performing incision at the position of greater corneal curvature. Temporal incision group showed less surgical induced astigamatic changes than superior incision.

To evaluate the abnormal positions of intraocular lens after cataract extraction and intraocular lens implantation, the study used the image analysis technique. Tilting and decent ration of posterior chamber intraocular lens(PCL) were studied according to the anterior capsulotomy. 103 patients(120 eyes) were randomized into 6 groups(20 eyes each) according to posterior chamber lens style and anterior capsulotomy type, and measured the degrees of tilting and decent ration of PCL by Scheimpflug camera. Three piece PCL implantation group showed significant less tilting than one piece PCL implantation group at postoperative 1 week. In one radial tear of anterior capsulotomy group, three piece PCL showed less tilting than one piece PCL. At postoperative 2 months, continuous curvilinear capsulorhexis without radial tear group showed significant less decent ration and tilting than one radial tear group. At postoperative 1 week and 2 months tilting of the continuous curvilinear capsulorhexis group was less than two or more radial tears group. As time passes from 1 week to 2 months tilting decreased significantly, but decentration did not showed significant decrease.

The effects of AMVISC(R) and Healon(R) in patients undergoing extracapsular cataract extraction with intraocular lens implantation were compared to the operative efficiency and postoperative reactions namely, inflammation, intraocular pressure, corneal endothelial damage, and corneal thickness. During the course of the cataract operations, twenty eyes received AMVISC(R) and twenty eyes received Healon(R). The AMVISC(R) and Healon(R) were all aspirated from anterior and posterior cha mbers by means of the irrigation and aspiration system at the end of the procedure. There were no significant difference in operative efficacy and postoperative reactions between AMVISC(R) group and Healon(R) group.
