Objective:
Toric intraocular lens implantation has been used to correct corneal astigmatism during cataract surgery. The study aimed to compare the visual outcomes between manual vs markerless toric intraocular lens implantation in astigmatic correction.
Methods:
The medical records of patients at American Eye Center who underwent phacoemulsification by multiple surgeons with insertion of monofocal or multifocal toric lenses via manual marking and markerless method from 2010-2019 were reviewed.
Results:
A total of 70 patients were included in the study. Results showed no significant difference in the following characteristics between manual and markerless method at one month and two months post-cataract surgery: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near vision acuity (UNVA), corrected near vision acuity (CNVA), refraction spherical equivalent. The UDVA, CDVA, UNVA, CNVA and astigmatism had significantly lower median/mean-rank at one and two months postoperatively compared to preoperative values.
Conclusion
In conclusion, our findings indicated that both manual-based and markerless systems effectively
facilitated accurate placement of the toric IOL on the desired axis. Notably, there was no significant difference observed between the two methods. Both systems are straightforward to execute. In low-resource settings like the Philippines, the manual marking method can be employed when markerless guidance equipment is unavailable.

Philippine Journal of Ophthalmology 2024;49(1):61-65
Objective:
To report a case of a suture-related corneal abscess caused by Enterococcus casseliflavus on a phacoemulsification corneal incision.
Method:
This is a case report.
Results:
An elderly female underwent complicated phacoemulsification surgery on the left eye requiring sutures
to seal the corneal incisions. Suture removal was incomplete at the side port, and a suture abscess developed
after 9 weeks. Cultures revealed heavy growth of Enterococcus casseliflavus which was initially treated with an
empiric broad-spectrum antibiotic (levofloxacin 1.5%) administered via intrastromal and subconjunctival
injections, followed by culture-guided topical and oral medications. The corneal infection resolved but
significant corneal thinning led to perforation, requiring a modified Gunderson flap procedure to repair the
defect.
Conclusion
Intrastromal and subconjuctival injection of levofloxacin 1.5% may be a viable empiric treatment
option for Enterococcus casseliflavus suture-related corneal abscess.

Objective:
To present a case of neovascular glaucoma secondary to ocular ischemic syndrome
following an uncomplicated phacoemulsification
Methods:
This is a case description of a 74-year-old male who developed blurred vision and increased
intraocular pressure (IOP) two months after an uncomplicated phacoemulsification cataract surgery
with posterior chamber lens implantation of the left eye. There was iris neovascularization with
absence of retinal dot/blot hemorrhages or neovascularization. The fluorescein angiogram (FA)
showed delayed choroidal fluorescence and arteriovenous time. IOP-lowering medications and
intravitreal injection of aflibercept were given. Carotid doppler test showed 70% stenosis of the
ipsilateral artery but a subsequent magnetic resonance angiography (MRA) did not show evidence of
significant stenosis.
Results:
At his last consultation, visual acuity improved to counting fingers. IOP was maintained at
12 mmHg with one anti-glaucoma medication.
Conclusion
Ocular ischemia can confound the outcome of an uncomplicated cataract surgery.
Doppler scans are usually chosen as the first-line exam for those suspected of carotid stenosis but, at
times, may have contradictory results with MRA.

Journal of the Korean Ophthalmological Society 2020;61(1):17-26
PURPOSE: In this study, we evaluated changes in the anterior chamber structure and lens position before and after phacoemulsification in eyes grouped by axial length (AL).METHODS: This study included 65 eyes (16 short eyes [AL < 22.5 mm], 33 normal eyes [22.5 mm < AL < 25.0 mm], and 16 long eyes [AL > 25.5 mm]) that underwent cataract surgery. Pre- and postoperative anterior chamber depth (ACD) was measured using Pentacam® and IOL Master®,. In addition, we evaluated the anterior chamber angle (ACA), anterior chamber volume (ACV), epithelium-iris distance, and iris-lens (intraocular lens [IOL]) distance.RESULTS: The change in ACD was significantly smaller in long eyes (Pentacam®,, p = 0.000; IOL Master®,, p = 0.001). The change in ACA was significantly larger in short eyes (p = 0.000), and the change in ACV was significantly smaller in long eyes (p = 0.000). The change in the epithelium–iris distance was significantly smaller in long eyes (p = 0.000), and the change in the iris-lens (IOL) distance was significantly smaller in short eyes (p = 0.000).CONCLUSIONS: In short eyes, changes in ACD, ACA, and ACV were found to be larger than those of other groups as the iris moved backward. In long eyes, greater backward movement of the IOL was observed. Therefore, the appropriate IOL power should be chosen, considering the postoperative position of the IOL during cataract surgery of short and long eyes.

PURPOSE: To report a patient with a pseudophakic bullous keratopathy (PBK) who underwent Descemet's membrane stripping endothelial keratoplasty (DSEK) with manual preparation of the donor corneal graft.CASE SUMMARY: A 61-year-old female presented with visual disturbance in her right eye. Five months prior, she was treated with phacoemulsification and intraocular lens exchange surgery of the right eye, and a very severe corneal edema was revealed by slit-lamp examination. We diagnosed PBK and planned DSEK with manual preparation of a donor corneal graft because of the non-availability of a microkeratome or a femtosecond laser. After making the corneal graft using an artificial anterior chamber, crescent knife and cornea dissector, the keratoplasty proceeded using the graft. Three months after surgery, her graft was well-maintained on the right eye. The patient's visual acuity was 0.3, and the corneal endothelial cell count was 1,844/mm².CONCLUSIONS: Manual preparation of the donor corneal graft for DSEK is suitable as a second choice treatment method when the availability of surgical devices is limited.

PURPOSE: To report two cases of postoperative endophthalmitis caused by Streptococcus dysgalactiae subspecies equisimilis (SDSE), which appeared as hyperacute presentation and panophthalmitis. CASE SUMMARY: A 68-year-old male was treated with cataract surgery and was evaluated the next day (less than 24 hours after surgery) because of acute loss of vision. There was severe inflammation and the visual acuity was light perception. The patient underwent pars plana vitrectomy (PPV) with intravitreal antibiotic injection. The vitreous culture revealed SDSE. After PPV, regression of inflammation was observed, although the corneal edema had progressed. The cornea evolved to decompensate due to bullous keratopathy and visual acuity of the eye decreased to no light perception after 3 months. A 87-year-old male who underwent phacoemulsification and intraocular lens implantation 2 days previously was hospitalized due to severe ocular pain and visual loss. There was severe inflammation, and the visual acuity was no light perception. The patient received only intravitreal injections of antibiotics due to severe corneal necrosis. The aqueous humor revealed SDSE. Four days after intravitreal injection, erythema and swelling of the eyelid of the affected eye was observed, and diagnosed as panophthalmitis. After treatment with intravenous antibiotics, cellulitis of the eyelid was resolved. The eye progressed as phthisis after 3 months without recurrence. CONCLUSIONS: Postoperative SDSE endophthalmitis showed aggressive and hyperacute presentation, resulting in blindness despite prompt treatment. SDSE is an emerging organism and should be considered a potential cause of postoperative endophthalmitis.

PURPOSE: We report a case of postoperative endophthalmitis in the cataract patient, associated with removal of an intralenticular foreign body that had remained in place without symptoms for 20 years. CASE SUMMARY: A 45-year-old male visited our outpatient clinic complaining of gradual visual loss in his right eye over the past 3 months. In slit-lamp examinations, anterior capsular opacification, nuclear sclerosis, and posterior subcapsular opacity were observed in the right eye. Twenty years before, a tiny metallic projectile had hit his right eye, but slit-lamp examination at the time of injury did not reveal any intraocular foreign body. We decided to undergo cataract surgery. During phacoemulsification, a metallic foreign body was found in the lens and safely removed; then an intraocular lens was implanted. As hypopyon was evident 3 days later, we injected intravitreal antibiotics and applied fortified antibiotic eye drops to the right eye. The anterior chamber inflammation improved and the best-corrected visual acuity recovered to 1.0. CONCLUSIONS: Surgeon should be aware of that endophthalmitis could develop after cataract surgery with removal of an intralenticular foreign body that had been in place for 20 years. But did not trigger inflammation or cause any symptoms as the cataract progressed.

9.Effect of Preoperative Factors and Gonioscopy on Intraocular Pressure Reduction after Phacoemulsification in Glaucoma
Yuli PARK ; Young Bin KIM ; Kyong Jin CHO
Journal of the Korean Ophthalmological Society 2019;60(5):463-469
PURPOSE: To evaluate a new gonioscopy score and preoperative factors as a potential predictor for intraocular pressure (IOP) reduction after phacoemulsification. METHODS: This is a retrospective review of 182 eyes with glaucoma of either open or narrow angles that underwent phacoemulsification. Preoperative variables such as age, IOP, refractive errors, anterior chamber depth (ACD), axial length, and lens position were evaluated at 6 months after surgery. A preoperative gonioscopy score was created, summing the Shaffer gonioscopy grading in 4 quadrants. To determine variables associated with IOP change at 6 months, univariate and multivariate linear regression analysis was performed. RESULTS: The mean age of the patients was 72.8 ± 9.5 years and the average preoperative IOP was 16.4 ± 3.7 mmHg with 1.2 glaucoma medications. The mean IOP reduction after phacoemulsification was 2.7 ± 2.2 mmHg at postoperative 6 months. Preoperative IOP (β = 0.55, p < 0.001), gonioscopy score (β = −0.29, p < 0.001), ACD (β = −0.67, p = 0.02), and IOP/ACD ratio (β = 0.58, p = 0.01) were associated with IOP reduction at 6 months. CONCLUSIONS: Preoperative predictors for IOP reduction after phacoemulsification were preoperative IOP, ACD, gonioscopy score, and IOP/ACD ratio in patients with glaucoma. The IOP/ACD ratio and gonioscopy score can be easy parameters to obtain and may help clinicians to estimate the IOP reduction after phacoemulsification.

10.Visual outcomes and intraoperative complication rates of Phacoemulsification Cataract Surgery by third year ophthalmology residents in the UP-Philippine General Hospital
Richard C. Kho ; Maria Angelica DF. Villano
Acta Medica Philippina 2019;53(4):350-354
Background:
Phacoemulsification is the most important cataract surgical procedure performed by ophthalmology residents. There is an increasing and consistent trend in international studies on decreased complication rates and more efficient surgical techniques with more surgeries performed. The data collected from this study can be used to quantitatively assess the cataract surgery training of Ophthalmology residents in the country and can help to improve the quality of cataract surgeries taught and performed in the training programs.
Objectives:
To analyze outcomes of phacoemulsification cataract surgeries and to determine the intraoperative complication rates of third-year residents of the University of the Philippines - Philippine General Hospital (UP-PGH).
Methods:
Retrospective chart review of phacoemulsification cases done by eight third-year ophthalmology residents at the UP-PGH from January 1 to December 31, 2017. Outcomes measured included postoperative best corrected visual acuity (BCVA), intraoperative complications (posterior capsular rent and vitreous loss), and adjusted phacoemulsification times (total phacoemulsification time multiplied by phacoemulsification power used).
Results:
Four hundred ninety-two (492) cases were analyzed. Postoperative mean BCVA was 20/25. There were no significant differences in visual acuity outcomes over the course of training. Intraoperative complications occurred in 33 cases, with fewer cases with posterior capsule rent and vitreous loss later in training after the first 50 cases. There was a downward trend of adjusted phacoemulsification time throughout training, with a significant difference between the first 50 and 100 cases.
Conclusion
Good visual outcomes are achievable throughout the resident’s phacoemulsification learning curve. Surgical competency in phacoemulsification, as measured by complication rates and phacoemulsification efficiency, still improves significantly with an increasing number of cases and experience beyond the first 100 cases.
