Culture-positive endophthalmitis after implantation of intraocular Collamer lens

Immediate versus delayed sequential bilateral ICL implantation: A retrospective comparison of vault height and visual outcomes

PURPOSE

To compare the visual outcomes and risks of suboptimal vault-related complications between immediate sequential bilateral ICL surgery (ISBICLS) and delayed sequential bilateral ICL surgery (DSBICLS).

DESIGN

A retrospective cohort study.

METHODS

Patients who underwent bilateral ICL implantation between November 2014 and December 2021 at the Eye and ENT Hospital of Fudan University (Shanghai, China) were included and divided into two groups: (1) ISBICLS: both eye surgeries performed on the same day, and (2) DSBICLS: second eye surgery performed < 7 days following the first one. Propensity score matching (PSM) was performed to compare the visual outcomes. Multivariable logistic regression models were used to estimate the odds ratios (ORs) of the suboptimal vaults.

RESULTS

Finally, 10,985 eyes were included. After PSM, 204 first surgery eyes and 162 s surgery eyes with complete postoperative data were matched. The safety and efficacy indices did not statistically differ between groups (all > 1.00), except that ISBICLS first surgery eyes achieved better efficacy index than DSBICLS group (1.03 ± 0.26 vs. 1.08 ± 0.23, P = 0.034). Excessive vault was observed in eight (4.06 %) ISBICLS first eyes, one (0.50 %) DSBICLS first eye, and none in the second surgery eye in either group. An insufficient vault was observed in one second eye and one DSBICLS second eye. We found no evidence of differences in the rate of excessive vault (OR = 0.831, 95 % CI: 0.426-1.622, P = 0.588) or insufficient vault (OR = 0.609, 95 % CI:0.062-5.850, P = 0.668).

CONCLUSION

ISBICLS provided safety, efficacy, and refraction predictability comparable to DSBICLS without increasing the risk of suboptimal vault-related complications.

Successful antibiotic management of Staphylococcus epidermidis endophthalmitis after implantable collamer lens implantation

PURPOSE

We report a case of successful medical management of endophthalmitis post implantable collamer lens (ICL) culture-positive of Staphylococcus epidermidis.

OBSERVATIONS

A 18-year-old female presented with decreased visual acuity in the left eye 20 days after ICL implantation. A diagnosis of postoperative endophthalmitis was made based on examination and ultrasonography. A vitreous tap was taken, and intravitreal antibiotics (vancomycin 1 mg/0.1ml and ceftazidime 2 mg/0.1ml) were administered twice (every 72 h), and peribulbar injection of triamcinolone acetonide after four days of the second intravitreal injection. The vitreous culture was confirmed for Staphylococcus epidermidis. The endophthalmitis was resolved, and visual acuity improved from 6/20 to 12/20 on day 7 and 22/20 on day 38. This is the first successful medical resolution of Staphylococcus epidermidis endophthalmitis post ICL surgery without ICL explantation and vitrectomy in the V4c model.

CONCLUSIONS AND IMPORTANCE

In antibiotic therapy, the excellent compliance and close follow-up of this endophthalmitis patient enabled careful postoperative surveillance on the effect of antibiotic therapy, avoiding the removal of the ICL or the loss of the integrity of the eye. The risk of potential infectious endophthalmitis post-ICL surgery should be fully emphasized during preoperative counseling.

Analysis of perioperative problems related to intraocular Implantable Collamer Lens (ICL) implantation

PURPOSE

To introduce a modified procedure of ICL implantation, to summarize the perioperative problems and their corresponding treatment after myopia correction with Implantable Collamer Lens (ICL), and to compare the difference of complications between the no-hole ICL and hole ICL.

METHODS

We searched all articles on ICL-related perioperative problems and their corresponding treatment in Scopus, Embase, PubMed and Web of Science databases for the last 22 years.

RESULTS

ICL implantation is safe, effective, stable and predictable in the correction of myopia, hyperopia and astigmatism, but can also cause a series of perioperative problems, including intraoperative and postoperative complications.

CONCLUSION

There are many kinds of complications related to ICL, but the common intraoperative and postoperative complications mainly include abnormality of arch height, abnormal position of ICL, loss of corneal endothelial cells and corneal decompensation, high intraocular pressure and secondary glaucoma, cataract and night vision symptoms. Compared with ICL without central pore, the incidence of complications such as loss of corneal endothelial cells and corneal decompensation, high intraocular pressure and secondary glaucoma and cataract was relatively lower in central hole ICL, while postoperative complications such as night vision symptoms were obvious.

Toric Implantable Collamer Lens for the Treatment of Myopic Astigmatism

Purpose

To report visual outcomes following surgical correction of myopic astigmatism with Visian Toric implantable collamer lens (ICL) (STAAR Surgical, Monrovia, CA, USA) at a single tertiary refractive center in the United States.

Patients and Methods

Toric ICL was implanted in 96 eyes (55 patients) with mean preoperative sphere of −8.98 ± 3.04 diopters (D) and cylinder of −2.67 ± 1.02 D from December 2018 to February 2021. Primary visual outcomes of efficacy, safety, stability, predictability of refractive correction, and astigmatic analysis were reported at three and twelve months postoperatively. Secondary subjective outcomes included patient-reported dry eye symptoms and glare/halos at postoperative visits. Other secondary outcomes were biometric data and postoperative vault over time.

Results

At three and twelve months, 75 and 46 eyes were evaluated, respectively. At twelve months, the mean manifest refraction spherical equivalent (MRSE) was −0.23 ± 0.47 D with 93% achieving within ±1.00 D of target refraction. The manifest refractive cylinder (MRC) at twelve months was −0.73 ± 0.51 D, with 86% within ±1.00 D of target. Uncorrected distance visual acuity (UDVA) was 20/20 or better in 74% of eyes at twelve months. No patients lost ≥2 lines of corrected distance visual acuity (CDVA) at twelve months. The mean angle of error was −0.9 ± 10.2° at three months and −1.6 ± 12.8° at twelve months. One patient required bilateral lens rotation, four patients underwent secondary enhancement with LASIK/PRK, and seven patients underwent postoperative limbal relaxing incisions.

Conclusion

This initial single-site experience finds Toric ICL implantation for myopic astigmatism to be safe and effective. Patients can achieve markedly improved UDVA in a single surgery with stable vision over time and minimal adverse subjective symptoms.

Culture-Negative C acnes Endophthalmitis Following Implantation of a Phakic Implantable Collamer Lens

Purpose:

This work describes a case of Cutibacterium acnes (formerly Propionibacterium acnes) endophthalmitis following a posterior-chamber, phakic, Implantable Collamer Lens (ICL) surgery.

Methods:

A 34-year-old previously healthy woman presented with chronic unilateral iritis 8 months after bilateral ICL surgery. Original testing revealed no cause for the iritis with normal culture, serology, and autoimmune testing results.

Results:

Follow-up revealed C acnes by polymerase chain reaction on vitrectomy samples. Complete resolution of symptoms was achieved following removal of the implant, lensectomy, and intravitreal antibiotics.

Conclusions:

We believe this is the first reported case of postphakic ICL C acnes endophthalmitis. It highlights the utility of polymerase chain reaction in cases of chronic uveitis.

Severe Intraocular Inflammation following Hydrophilic Acrylic Phakic Intraocular Lens Implantation in A Case with Concealed History of COVID-19: A Case Report and Literature Review

Purpose: To firstly present management of toxic anterior segment syndrome (TASS) and possible postoperative endophthalmitis (POE) after implantation of a new hydrophilic-acrylic posterior chamber (PC) phakic intraocular lens (pIOL) in a case with undeclared history of COVID-19.Methods: A 21-year-old male without known disease represented severe anterior chamber inflammation (hypopyon), poor vision and corneal edema without vitreous involvement (TASS) at 24-hours after PC-pIOL implantation for unilateral high myopia (amblyopic).Results: Preoperative best-corrected visual acuity (BCVA) was 0.2 OS (-13 diopters). At 56-hours, vitreous was involved with visual loss indicating POE. The patient confessed that he had COVID-19 1-month ago. COVID-19 immunoglobulin M/G tests were positive, while other markers were negative. Intracameral/intravitreal antibiotics were applied. BCVA was 0.15 without hypopyon at 24-hours. Cultures were negative. Final BCVA was 0.6 with normal examination.Conclusion: TASS/POE etiology could not be demonstrated in this case, whereas COVID-19-related proinflammatory systemic background could have effect on triggering/aggravating this scenario.].

Atypical endophthalmitis after intraocular collamer lens implantation

Unilateral endophthalmitis occurred after bilateral immediately sequential intraocular collamer lens (Visian Implantable Collamer Lens) implantation for the correction of myopic astigmatism in a 49-year-old woman. The surgeries and initial recovery were unremarkable. However, after 3 days, the patient noticed increasing blurring of vision in the left eye and presented to our clinic. The anterior segment of this eye was quiet, while the vitreous cavity was densely infiltrated. Immediate explantation of the corrective lens and vitrectomy combined with intravitreal antibiotic injection were performed. Staphylococcus epidermidis was detected in the vitreous tap and treated with intravenous antibiotics, antibiotic eyedrops, and parabulbar injections of dexamethasone. The corrected distance visual acuity recovered to 20/20 over a 6-month period. However, a cataract developed thereafter.

Successful re-implantation of implantable collamer lens after management of post-ICL methicillin-resistant Staphylococcus epidermidis endophthalmitis

A 29-year-old man presented with acute onset pain, redness and diminution of vision in the right eye 5 days after implantation of an implantable collamer lens (ICL). A diagnosis of postoperative endophthalmitis was made based on examination and ultrasonography. A vitreous tap was taken and intravitreal antibiotics (vancomycin 1 mg/0.1 ml+piperacillin-tazobactam 225 µg/0.1 mL) were administered. The vitreous culture revealed presence of methicillin-resistant Staphylococcus epidermidis. There was minimal improvement after 48 h; hence the ICL was explanted and repeat injection of intravitreal antibiotics administered. Following this, the endophthalmitis resolved and the patient achieved a corrected distance visual acuity of 20/25 4 weeks later. A repeat implantation of ICL was performed 9 months after the first surgery, following which the patient regained uncorrected distance visual acuity of 20/20. To our knowledge, this is the first case in which an ICL was re-implanted after successful resolution of endophthalmitis.

Endophthalmitis Caused by Rhizobium radiobacter After Posterior Chamber Phakic Intraocular Lens Implantation to Correct Myopia

PURPOSE

To describe a 29-year-old man presenting with acute-onset endophthalmitis caused by Rhizobium (formerly Agrobacterium) radiobacter after uneventful implantable collamer lens implantation for myopia.

METHODS

Case report.

RESULTS

The patient was treated with intravitreal injections of vancomycin and ceftazidime, as well as topical and systemic antibiotics. The patient had a good response with a final visual acuity of 20/50 at the last follow-up visit 25 months postoperatively.

CONCLUSIONS

This case represents the first case report of endophthalmitis caused by Rhizobium radiobacter following implantable collamer lens implantation.

Long-term refractive outcomes of posterior chamber phakic (spheric and toric implantable collamer lens) intraocular lens implantation

To report the long-term refractive outcomes, safety, predictability, efficacy and complications of 349 eyes treated with posterior chamber phakic intraocular lenses (pIOLs). A retrospective review of consecutive clinical cases of patients who underwent spheric implantable collamer lens (ICL) and toric ICL (TICL) implantation. The study included 349 eyes of 216 patients with sphere between +8 to −24 diopters (D) and 0 to −6.5 D of astigmatism. Statistical analysis was performed to identify differences between preoperative and postoperative refractive outcomes. Main outcome measures were preoperative and postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical and cylindrical errors and spherical equivalent and significant postoperative complications. 194 eyes were treated with TICL and 155 eyes with ICL. The mean age of the patients was 29 ± 6.7 years. The mean preoperative sphere was −10.35 ± 5.1 D (+8 to −24) and the postoperative sphere was −0.09 ± 1.06 D (+3.25 to −6.5), p < 0.001. Preoperative cylinder was −2.63 ± 1.44 (0 to −6.5 D) and postoperative cylinder was −0.97 ± 0.89 D (0 to −3.5), p < 0.001. The preoperative mean spherical equivalent was −11.6 ± 5.12 D (+7.875 to −25.625) and postoperative spherical equivalent was −0.52 ± 1.03 (+2.25 to −6.75), p < 0.001. The mean preoperative UDVA was 1.72 ± 0.49 and postoperative UDVA was 0.23 ± 0.22, p < 0.001. The mean preoperative CDVA was 0.21 ± 0.17 and postoperative CDVA was 0.12 ± 0.138, p < 0.001. The implantation of posterior chamber pIOLs is a safe, predictable and effective strategy to manage refractive errors during long-term follow-up.

Implantable collamer posterior chamber intraocular lenses: a review of potential complications

PURPOSE

To review the peer-reviewed literature reporting postoperative complications of the most recent models of Visian Implantable Collamer posterior chamber intraocular lenses (ICL, STAAR Surgical Co).

METHODS

A literature search of the PubMed database was performed to identify all articles related to ICL complications. Articles were obtained and reviewed to identify those that reported complications using the latest ICL designs.

RESULTS

Cataract was the major postoperative complication reported: 136 (5.2%) in 2592 eyes. Of those, 43.4% (n=59) were reported within 1 year, 15.4% (n=21) between 1 and 3 years, and 35.3% (n=48) ≥ 3 years after ICL implantation. Twenty-one (15.4%) cataracts were reported as surgically induced, 46 (33.8%) eyes had poor vault (<200 μm), and cataract surgery was carried out in 27.9% (n=38) of eyes. Early acute intraocular pressure increase was also reported to be relatively frequent, whereas acute pupillary block was less frequent and mostly resolved with additional iridotomies. A total of 42 ICLs were explanted due to cataract and IOP. Reported endothelial cell loss varied from 9.9% at 2 years to 3.7% 4 years postoperatively. This loss was reported to be more pronounced within the first 1 to 2 years, with stability or lower progression after that time.

CONCLUSIONS

The majority of reported complications after ICL implantation are cataract formation. The improvements in lens geometry and more accurate nomograms applied to the selection of the lens to be implanted, in addition to the surgeon's learning curve, might be factors in the decreased occurrence of postoperative complications reported currently.
