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.

OBJECTIVE:
To evaluate the effect of different cumulative energy composite parameters on the outcomes of phacoemulsification cataract surgery in patients with type 2 diabetes mellitus.
METHODS:
A total of 252 patients with cataract (involving 252 eyes) and type 2 diabetes mellitus received phacoemulsification cataract surgery in our hospital between January, 2017 and June, 2019. The patients were divided into group A (150 cases) and group B (102 cases) for cataract phacoemulsification with cumulative energy composite parameters of 8 and 10, respectively, and 90 nondiabetic patients received cataract phacoemulsification with a cumulative energy composite parameters of 10 served as the control. The macular thickness, best corrected visual acuity, visual acuity, and postoperative leakage in the 3 groups were evaluated at 1 week, 1 month, and 3 months after the surgery.
RESULTS:
The visual acuity was significantly improved after phacoemulsification better in all the 3 groups. At 3 months after the surgery, the proportions of patients with visual acuity ratio < 0.1 or >1.0, macular thickness, best corrected visual acuity and permeability differed significantly between groups A and B ( < 0.05), but not between group A and the control group ( > 0.05). At 1 month and 3 months after the surgery, the proportion of patients with visual acuity ratio < 0.1 was significantly lower and the rate of visual acuity ratio >1.0 was higher in group A than in group B. At 1 month after the operation, the total leakage rate in group A (31.1%) was higher than that in the control group (21.1%) but comparable with that in group B; at 3 months, the total leakage rates were significantly lower in group A than in group B (10.0% 32.4%, < 0.05), and the leakage resulted mainly from local and diffuse permeation.
CONCLUSIONS
Phacoemulsification can effectively improve the visual acuity of cataract patients especially in non-diabetic patients. A lower cumulative energy composite parameter achieves better outcomes in type 2 diabetic patients with cataract. The macular thickness, local infiltration and diffuse leakage can be used as indicators for assessing visual recovery and stabilization after phacoemulsification.

OBJECTIVE:
To evaluate the application of femtosecond laser technology in the management of subluxated lens.
METHODS:
We retrospectively analyzed the data of the patients with subluxated lens undergoing femtosecond laser- assisted surgery at the Cataract Center of Guangzhou Aier Eye Hospital between March, 2017 and May, 2019. The LenSx femtosecond laser-assisted cataract surgery system was used to perform capsulotomy and lens fragmentation. According to the patients' eye condition, anterior vitrectomy was performed and capsular retractors was used. After phacoemulsification, I/A and insertion of the tension rings, the intraocular lens (IOL) was implanted into the capsular bag. The perioperative data, complications, visual acuity and intraocular pressure after the operation were recorded, and the stability of the capsular bag and IOLs were assessed.
RESULTS:
We analyzed the data of 25 cases (29 eyes) of subluxated lens, including 16 (16 eyes; 55.17%) as the result of traumatic lens subluxation, 5 (9 eyes; 31.03%) of Mafan syndromes, 1 case (1 eye; 3.45%) of high myopia and 3 cases (3 eyes; 10.34%) of unknown causes. Thirteen 13 eyes (44.83%) showed mild subluxation, 7 (24.14%) had moderate subluxation, and 9 (31.03%) had severe subluxation. Femtosecond laser- assisted capsulorhexis, lens fragmentation and phacoemulsification were successfully completed for 29 eyes, of which 28 eyes (96.55%) retained the complete capsular bag and with successful implantation of the capsular tension devices and IOLs. Nine eyes (31.03%) were treated with anterior segment vitrectomy; iris hooks were used for 2 eyes (6.90%) and capsular bag hooks for 9 eyes (31.03%). The best corrected visual acuity was significantly improved in 29 eyes after operation ( < 0.05). At 1 month after the surgery, 26 eyes (89.66%) showed stably centered IOLs, 2 eyes (6.90%) showed slight tilt of the IOLs, and 3 eyes (10.34%) had anterior capsular contraction. The intraoperative complications included subconjunctival hemorrhage (75.87%), incomplete capsulotomy (17.24%) and contracted pupils (13.79%).
CONCLUSIONS
The application of femtosecond laser assisted technology enhances the surgical safety and effectiveness for subluxated lens, facilitates the choice of individualized surgical options, and promotes maximum recovery of the patients' visual function.

OBJECTIVE:
To observe the effects of acupuncture combined with phacoemulsification for cataract with glaucoma.
METHODS:
Sixty-eight patients with cataract and angle-closure glaucoma were randomly divided into an observation group and a control group, 34 cases in each one. The patients in the control group were treated with phacoemulsification. Based on the treatment in the control group, the patients in the observation group were treated with and acupuncture at acupoints around eyes; the treatment was given once every other day, and 15-day treatment constituted a course, and 2 courses (60 days) were given. The intraocular pressure (IOP), visual acuity, pain severity, aqueous outflow (F value) and clinical symptoms were observed in the two groups before treatment and after 1 d, 7 d, 30 d and 60 d of treatment.
RESULTS:
The IOP after 1 d, 7 d, 30 d and 60 d of treatment in the observation group was lower than that in the control group (all <0.05), while the visual acuity after 7 d, 30 d and 60 d of treatment in the observation group was higher than that in the control group (all <0.05). Compared before treatment, the IOP was significantly decreased after 1 d, 7 d, 30 d and 60 d of treatment in the two groups, and the visual acuity was significantly increased after 7 d, 30 d and 60 d of treatment in the two groups (all <0.05). The pain scores and F value after 7 d, 30 d and 60 d of treatment in the observation group were lower than those in the control group (all <0.05). Compared before treatment, the pain scores and F value after 7 d, 30 d and 60 d of treatment were significantly reduced in the two groups (all <0.05). After 60 d of treatment, the number of patients who presented general clinical symptoms in the observation group was significantly lower than that in the control group (<0.05).
CONCLUSION
Based on phacoemulsification, acupuncture and could significantly reduce the IOP and F value, relieve pain and improve visual acuity in patients with cataract and glaucoma.

PURPOSE: To report a case of macular edema and retinal vasculitis treated with intravitreal dexamethasone implantation in a Behcet's disease patient after cataract surgery. CASE SUMMARY: A 26-year-old male with Behcet's disease, without recurrence of uveitis for 3 months, underwent phacoemulsification and posterior chamber intraocular lens implantation for a cataract in the left eye. The preoperative best corrected visual acuity (BCVA) of the left eye was 0.15. At day 1 after surgery, his BCVA was 0.4, and slit lamp examination of his left eye revealed a mild anterior chamber reaction. At 1 week after surgery, he presented with left vision impairment, his BCVA was 0.04, and mild inflammation was observed in both the anterior chamber and the vitreous in his left eye. Unilateral macular edema was confirmed with optical coherence tomography, and fluorescein angiography revealed retinal vasculitis on the fovea and peripheral retina. Intravitreal dexamethasone implantation was performed in his left eye, 1 month after treatment, the macular edema and retinal vasculitis had improved, and the BCVA of his left eye was 0.8. CONCLUSIONS: In patients with Behcet's disease, intravitreal dexamethasone implantation can be an effective treatment option for macular edema and retinal vasculitis after cataract surgery.
