During 1997-1998, 272 operations were performed, their 94.85% successfully with an affordable cost of 150,000 - 200,000 VND for each cases.

During 1992-1997 year period, 41 eyes with the loss of posterior capsula were submitted to a surgery of insertion of artificial vestibular vitreous lens of S. flex from Alcon firm. Results affirmed its proper application in all cases. The possible complications were noted lately in some cases such as oedema, dystrophy of the cornea and a raise of ocular tension. The dimention of the lens and the exact location of the artificial lens were also the problems of concern

Blindness prevalence and its causes are necessary for planning of the Blindness Prevention activities. Objectives: to evaluate blindness prevalence and causes, the output and outcome of cataract surgical services in the community. Methods: Cross-sectional prescriptive study was conducted on 1,729 persons of 50 years old and over. Results: Bilateral blindness prevalence is 3.41%, monocular blindness prevalence is 7.63% in the group of 50 years old and over. Main causes of blindness are cataract (47.5%), pathology of posterior segment (22.0%), glaucoma (16.9%), trachoma (3.4%). Bilateral and monocular cataract-related blindness rates are 1.50% and 3.76%, respectively. Prevalence of TT in one eye is 4.22%, in both eyes is 2.66%, prevalence of Pterigyum in one eye is 19.56% and in both eyes is 7.99%. The bilateral aphakia rate is 1.39%, monocular aphakia rate is 2.37%. The cataract surgical coverages are 63.89% of patients and 43.20% of eyes. The successful surgical rate is 67.42%. Main barriers for cataract management service are poverty (23.1%), unawareness (18.2%), and no accompaniers (9.1%). Conclusions: Main cause of blindness in Hanam is still cataract. The CSSR is good but the successful surgical rate is not high. In the next 10 years promotion of cataract surgery output and surgical quality should be done in order to reduce blindness prevalence.

In 2000 – 2002 year period, in the Central Institute of Ophtalmology, 54 children aged from 0 –14 years with monocular or binocular congenital cataract, underwent a tunnel operation without suture. Results showed that the sclero-corneal tunnel surgery without suture was efficient for treating congenital cataract. A straight incision through ½ of the sclera thickness was advisable. Cutting edge of the scleral should be help parallelly to the scleral surface

Objectives: Video-based learning of surgical skills is a useful complement in training programs. This is more evident where direct patient exposure is limited due to multiple factors. In ophthalmic surgery, access to high quality ocular surgery videos such as for cataract operations, can provide significant learning points for trainees in an institutional program. Creation therefore of a local, curated, and indexed library of cataract surgery would support alternative means to maximize training of new ophthalmic surgeons. The objective of the project was to develop a local library of cataract surgery videos as an adjunct teaching tool for resident trainees in a Philippine tertiary eye care center. Methods: A collection of cataract surgery videos from 2013-2020 were compiled into a single workstation. Videos were reviewed and catalogued using set keywords for easy searchability and labelling. Results: 256 videos of cataract surgeries were compiled into the library. 6 main headings for the keywords, with 159 total subheadings were established to provide robust tagging and search options to index the video. Conclusion Particularly in Ophthalmic surgery, refinement of surgical technique is essential in ensuring better postoperative visual outcomes. This is achieved through repetition and careful dissection of operative technique. The use of a library with multiple videos of a similar procedure allows trainees more exposure to certain cases. This ultimately affords trainees, better experience and confidence in their own surgeries.

The study was conducted on 20 patients with bilateral lens luxation (40 eyes) and 30 patients with lateral lens luxation (30 eyes), total 70 eyes. All patients were under 25 years old. The results showed that using the vitrectomy Erbe device in lens luxation removal is application of advanced achievements in our condition. It allows achieving the best surgical outcome for lens luxation, giving facilities for inserting artificial lens in later and contributing to regaining the vision of patients. This technique can be applied in facilities where the vitrectomy devices are available for all patients with lens luxation who have indication of operation

A study on the patients with the dislocation and luxation of lens were received an surgical treatment in the Institute of Pediatry from 8/1992 was carried out. Objectives were the clinical features, the methords of surgery and techniques of insert of lens. The results: the dislocation of lens occurred more frequently than the luxation of lens. The method of surgery depends on the age and the clinical conditions

PURPOSE: The axial length measurement is an important variable in calculating the intraocular lens (IOL) power in cataract surgery. In this study, the effects of the implantable collamer lens (ICL) on the axial length measurement were investigated. METHODS: The axial lengths of 141 eyes of 76 highly myopic patients were measured before ICL implantation and 1 month postoperatively using applanation A-scan ultrasound. RESULTS: The measured axial lengths before ICL implantation and 1 month after the surgery were 28.03 +/- 1.91 mm and 28.08 +/- 1.86 mm respectively, with a statistically significant difference of 0.05 mm (p = 0.036). These 2 values showed a high correlation (R2 = 0.9829, p < 0.0001). CONCLUSIONS: Even though the axial length after ICL implantation significantly increased, the 0.05 mm change was too small to influence the determination of the IOL diopters in cataract surgery. Therefore, ICL implantation history may be reflected when measuring the axial length for the IOL power calculation in cataract surgery, but the axial length measured immediately before the cataract surgery may be used to calculate the IOL power regardless of the ICL implantation history.

To report acute onset lens particle glaucoma associated with a spontaneous anterior capsular dehiscence. A 66-year-old man presented with spontaneous anterior lens capsule dehiscence with an acute onset of right eye pain that was associated with white particles in the anterior chamber angle and intraocular pressure (IOP) of 55 mmHg. No trauma or other inflammatory antecedents were reported. A hypermature cataract was observed at slit lamp exam. After medical treatment without IOP control, we performed extracapsular cataract extraction and anterior vitrectomy. Anterior chamber aspirate confirmed the presence of macrophages. The postoperative IOP at one month was 16 mmHg OD without medication. Spontaneous dehiscence of the anterior lens capsule in a patient with a hypermature cataract may release lens cortical material, resulting in lens particle glaucoma. Prompt surgical removal of the lens material usually controls the high IOP, and the need for additional glaucoma surgery is not common.

14 eyes of 11 patients with chronic angle-closure glaucoma(CACG) undergoing extracapsular cataract extraction(ECCE) with posterior chamber intraocular lens(PCIOL) implantation(group 1) and 14 eyes of 12 patients without glaucoma undergoing ECCE/PCIOL(group 2) were studied to assess the effect on anterior chamber depth, anterior chamber angle, and intraocular pressure (IOP). We measured the anterior chamber depth and angle using the EAS-1000 Scheimpflug camera. Following ECCE/PCIOL in group 1, the anterior chamber depth increased 1.00 +/- 0.25mm(p=0.0001), the anterior chamber angle widened 15.36 +/- 5.61 degrees(p=0.0001), and the postoperative IOP drop of 4.7mmHg(23.9%) showed statistical significance. Group 2 showed the increase of anterior chamber depth 0.22 +/- 0.44mm(p=0.0964), the widening of anterior chamber angle 2.51 +/- 2.65 degrees(p=0.0047), and the decrease of IOP 0.9mmHg(6.2%, p=0.0933). The effects on anterior chamber depth, anterior chamber angle, and rap were statistically significant between the two groups. Based on these results, we recommend that eyes with cataract and CACG may be considered for ECCE/PCIOL implantation as a first procedure rather than combined cataract and filtering surgery.
