Abstract
Introduction Calcification of hydrophilic intraocular lenses (IOL) is a rare complication following cataract surgery. Secondary calcification is described as due to host factors or changes in the IOL environment and uveitis, proliferative diabetic retinopathy and sequelae of ocular surgery are recognised potentiators. The impact of systemic connective tissue disease on IOL opacification is yet to described. Purpose To describe the clinical presentation and management of a young patient, with a rare subtype of Ehlers-Danlos syndrome, who presented with secondary IOL calcification 14 years after primary IOL insertion. Observations Floret-like lesions were observed on the IOL surface. Positive staining for calcification was observed with Alizarin red and von Kossa method on laboratory analysis. Conclusions and importance Patients with systemic connective tissue disease, such as a subtype of Ehlers-Danlos, may present with secondary IOL calcification many years after primary lens insertion. This poses an additional consideration when implanting IOLs in these patients.Good visual acuity can be achieved with IOL exchange.

Abstract
PURPOSE To report the long-term clinical outcomes of transscleral four-point fixation of Akreos intraocular lens using a closed continuous-loop suture technique. METHODS This was a retrospective, multicenter, interventional case series. Primary outcome measures were best-corrected visual acuity, intraocular pressure, corneal endothelial cell density, and complications with a minimum of 1-year follow-up. RESULTS One hundred and ninety-two eyes of 177 patients from two surgical hospital sites were identified. The mean best-corrected visual acuity improved from 0.88 ± 0.74 logarithm of the minimum angle of resolution (Snellen 20/152) preoperatively to 0.42 ± 0.52 logarithm of the minimum angle of resolution (Snellen 20/53) postoperatively ( P < 0.001). The mean preoperative intraocular pressure was 17.51 ± 8.67 mmHg, and the mean postoperative intraocular pressure at final follow-up was 15.08 ± 4.18 mmHg ( P = 0.001). The mean corneal endothelial cell density significantly reduced from 2,259 ± 729 cells/mm 2 to 2077 ± 659 cells/mm 2 , representing a cell loss of 5.73% ( P < 0.001). The intraocular lens was fixed well during follow-up. There were no intraoperative complications noted. Postoperative complications included transient ocular hypertension in 15 eyes (7.81%), hypotony in two eyes (1.04%), retinal detachment in one eye (0.52%), and macular edema in one eye (0.52%). CONCLUSION The transscleral four-point fixation Akreos intraocular lens using the closed continuous-loop suture technique was effective and safe with satisfactory visual acuity with a minimum of 1-year follow-up.

Abstract
PURPOSE To report three cases of postoperative opacification of sutureless scleral-fixed hydrophilic intraocular lens (FIL SSF IOL, Soleko, Italy) after gas tamponade. Two cases occurred after pars plana vitrectomy and one case after Descemet membrane endothelial keratoplasty. CASE REPORT Two diabetic patients underwent a FIL SSF IOL implantation after posterior capsular rupture during cataract surgery. Rhegmatogenous retinal detachment (RRD) was observed in one patient during the initial surgery. A second patient developed a RRD five months after surgery. Both RRDs were treated with pars plana vitrectomy and perfluoroethane (C2F6) gas tamponade. A few days after the surgery, C2F6 was observed in the anterior chamber of both patients. Two months after gas tamponade, opacification of the anterior surface of the IOL was observed. The third patient was a 74-year-old woman, who underwent a combined Descemet membrane endothelial keratoplasty (DMEK) and FIL SSF IOL implantation. Two rebubblings with sulfur hexafluoride (SF6) retreatments were required due to corneal graft detachment. One month later, an opacification of the anterior surface of the IOL was observed. Explantation with implantation of iris-claw IOL was decided, which resulted in an improvement of BVCA. Analysis of the IOL showed a positive Von Kossa staining, indicating calcification of the IOL. We performed a review of all the cases of FIL SSF IOL implantation in our centers. The overall rate of FIL SSF IOL opacification was 2.1% (3/140). Amongst patients treated with gas tamponade, the rate of opacification was 27.3% (3/11). Although FIL SSF IOL implantation appears to be an effective option for the treatment of aphakia, caution should be exercised regarding the risk of opacification following gas tamponade, especially since these patients are at risk of retinal detachment.

Abstract
BACKGROUND To report a case of membranous encapsulation of a scleral-fixated Akreos intraocular lens (IOL) that was successfully treated with vitrectomy and membranectomy without IOL exchange or removal. METHODS Case report. RESULTS A 58-year-old woman with a history of bilateral chronic anterior and intermediate uveitis underwent scleral fixation of Akreos IOL for dislocated 3-piece IOL in the vitreous cavity. She presented one year later with progressively worsening vision (decreased to 20/200) and was found to have a complete encapsulation of the IOL. The patient underwent successful vitrectomy and membranectomy with return of vision to 20/25 within three months of surgery. CONCLUSION There are numerous case reports of opacification after scleral fixation of Akreos IOL. To our knowledge, this is the first report of complete encapsulation of the IOL with a membrane of this type and character. The etiology for this patient's presentation is unclear, but was presumed to be related to her history of chronic intraocular inflammation.

Abstract
PURPOSE Scleral fixation of intraocular lenses constitutes a surgical option in cases where there is inadequate capsular support or zonular insufficiency. Knotless techniques, such as the z-suture technique, avoid suture-related complications, such as conjunctival erosion or exposure. The purpose of this study was to evaluate the visual outcomes and postoperative complications of patients who underwent scleral z-suture fixation of the Akreos AO® intraocular lenses. METHODS A retrospective, observational study was conducted, including 22 eyes of 20 patients who underwent Akreos AO® intraocular lenses using the z- suture scleral fixation technique. RESULTS The mean age of the patients was 55,64 ± 28,47 years old, and the mean follow-up time was 25,64 months. The most common indication for surgery was previous complicated cataract surgey. The mean postoperative spherical equivalent was +0,058D ± 0,79D, with values ranging from - 1,50D to +1,00D. Mean best-corrected visual acuity was 0,178 ± 0,15 logMAR. Intraocular pressure was 15,07 ± 2,56 mmHg on the day after surgery, and 16 ± 2,15 mmHg 1 month after. No suture-related complications were observed in any patient postoperatively. One patient had a slight inferonasal lens dislocation and another patient had a severe case of herpetic keratitis posoperatively. DISCUSSION The knotless z-suture technique appears to be a reliable and safe way to fix an intraocular lens in the sclera, regardless of the patient's age. Our results show good visual results and predictable refractive outcomes. Decades of follow-up may be necessary to assess the long-term risk of lens dislocation.

Abstract
PURPOSE To report the results of a novel surgical four-point transscleral suture fixation of intraocular lens (IOL) with four hollow haptics using the double-suture technique. METHODS We retrospectively reviewed the medical records of 15 eyes of 15 patients who underwent 4-point transscleral suture fixation of a foldable IOL using the double-suture technique. Preoperative data and follow-up data for at least 4 months were collected for all patients. RESULTS The IOLs were fixed and centered well. The mean preoperative corrected distance visual acuity was 0.70 ± 0.54 logarithm of the minimum angle of resolution (Snellen 20/102), and it improved to 0.29 ± 0.26 logarithm of the minimum angle of resolution (Snellen 20/39) at the final follow-up ( P = 0.001). No vitreous hemorrhage, hypotony, suture breakage, retinal detachment, IOL dislocation, and iris capture was detected during the follow-up period in any of the patients. CONCLUSION We have developed a novel technique for 4-point transscleral suture fixation of IOL using the double-suture technique with 9-0 polypropylene suture. This technique seemed to be safe and it may not require the surgeon to learn any new technique.

Abstract
AIM To determine the clinical risk factors that may increase the occurrence of intraocular lens (IOL) calcification in patients who had undergone pars plana vitrectomy (PPV). METHODS The medical records of 14 patients who underwent IOL explantation due to clinically significant IOL opacification after PPV were reviewed. The date of primary cataract surgery, technique and implanted IOL characteristics; the time, cause and technique of PPV; tamponade used; additional surgeries; the time of IOL calcification and explantation; and IOL explantation technique were investigated. RESULTS PPV had been performed as a combined procedure with cataract surgery in eight eyes and solely in six pseudophakic eyes. The IOL material was hydrophilic in six eyes, hydrophilic with a hydrophobic surface in seven eyes and undetermined in one eye. The endotamponades used during primary PPV were C2F6 in eight eyes, C3F8 in one eye, air in two eyes and silicone oil in three eyes. Two of three eyes underwent subsequent silicone oil removal and gas tamponade exchange. Gas in the anterior chamber was detected in six eyes after PPV or silicone oil removal. The mean interval between PPV and IOL opacification was 20.5 ± 18.6 months. The mean BCVA in logMAR was 0.43 ± 0.42 after PPV, which significantly decreased to 0.67 ± 0.68 before IOL explantation for IOL opacification (p = 0.007) and increased to 0.48 ± 0.59 after the IOL exchange (p = 0.015). CONCLUSIONS PPV with endotamponades in pseudophakic eyes, particularly gas, seems to increase the risk for secondary IOL calcification, especially in hydrophilic IOLs. IOL exchange seems to solve this problem when clinically significant vision loss occurs.

Specifying Risk of Intraocular Lens Opacification After Endothelial Keratoplasty for Different Intraocular Lens Models: A Retrospective Monocentric Cohort Study. Cornea 2022:00003226-990000000-00119. [PMID: 36633939 DOI: 10.1097/ico.0000000000003087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 05/18/2022] [Indexed: 01/13/2023]
Abstract
PURPOSE The aims of this study were to calculate the specific risk of opacification for different intraocular lens (IOL) models and to determine whether differences exist, even between lenses made of similar acrylic materials. METHODS This is a retrospective cohort study of all patients who underwent endothelial keratoplasty (EK), either after or in conjunction with cataract surgery, from June 2009 to October 2020 at Fundación Jiménez Díaz Hospital. RESULTS Three hundred seventy-two eyes of 308 patients with a median follow-up of 856 days [interquartile range (IQR): 384-1570] were included, of which 128 IOLs were hydrophobic, 120 hydrophilic, and 124 unknown. 12.9% of IOLs opacified after a median of 466 days (IQR: 255-743). Visual acuity (VA) was significantly lower in the opacified IOL group [0.51 (IQR: 0.36-1.13)] compared with the nonopacified group [0.22 (IQR: 0.11-0.65)] ( P < 0.001). IOL explantation and exchange was performed in 10 eyes, in which VA improved markedly, from 1.75 (IQR: 0.99-3.00) to 0.60 (IQR: 0.36-0.86) ( P = 0.004). IOL material and opacification events were not independent ( P < 0.001). Significant differences were found between the Akreos ADAPT AO and MI60P models and the Asphina 409M model ( P = 0.022). No significant differences were found in the opacification ratio for hydrophilic IOLs in the clinical diagnosis ( P = 0.11), the type of EK ( P = 0.25), the rebubbling rate ( P = 0.44), or the tamponade used ( P = 0.36). CONCLUSIONS Hydrophilic lenses should be avoided in patients at risk of requiring EK. It is important to know the probability of opacification of each IOL model to balance risk and benefits when planning an EK procedure because not all lenses opacify equally. Opacification is an unwanted event with a negative impact on VA, making IOL explantation and exchange the only viable treatment, although one that is not without risks.

Abstract
Background While each scleral fixation method has its own advantages, there is a lack of strong evidence to suggest a superior technique. Advances in cataract surgery expand patient eligibility for successful cataract extraction, benefitting a growing population of pseudophakic patients. However, implantation of secondary intraocular lens (IOL) with compromised anterior or posterior capsule is a more challenging task. Each method of scleral fixation has its own advantages and none of them has strong evidence to be superior. This paper describes postsurgical outcomes of two scleral intraocular(IOL) fixation techniques combined with pars plana vitrectomy(PPV) from a single tertiary referral eye center. Methods Patients underwent PPV and IOL implantation with either four-point sutured scleral fixation (Akreos AO60(AK); n = 24) or two-point sutureless flanged intrascleral fixation (CT Lucia(CTL); n = 7). Reports include IOL and sclerotomy placement, fixation techniques, and IOL model. Results Thirty-one eyes of thirty patients were analyzed. Average change in vision from baseline measurement was LogMAR − 0.68 ± 0.66 and − 0.90 ± 0.63 for AK and CTL groups, respectively. Average postoperative refractive error was − 0.3 ± 1.03 D (AK) and 0.4 ± 0.60 D (CTL). No opacification cases of Akreos lens were found in this study with the longest follow up of 53 months. Conclusions Both methods of implantation (sutured and sutureless) could provide good visual and refractive outcomes. Minimal complication rates were reported despite including patients with multiple comorbidities, making both techniques an attractive choice for secondary IOL implantation.

Abstract
Background The main options for intraocular lens (IOL) placement without capsular bag support and/or zonular weakness are iris-fixated IOL and scleral-fixated IOL (SFIOL). Purpose To describe the surgical technique and the outcomes of intrascleral knotless zigzag suture fixation of Akreos AO60 foldable IOL. Methods Retrospective cohort study of consecutive cases. Results Ninety-nine eyes of 92 patients were retrospectively studied. The mean age was 72.1±15.2 years (range 18–94), and the median follow-up duration was 19.5 months (range 3–81). The best-corrected visual acuity improved from a mean±SD of 1.34±0.70 logarithm of the minimum angle of resolution (logMAR) units at baseline to 0.49±0.56 logMAR at the end of follow-up (p<0.001). The mean±SD final SE was −1.24±1.82 diopters. The mean±SD prediction error was −0.51±1.16 diopters. The overall perioperative complications rate was 44.4% (n=44). The rate of complications requiring invasive treatment was 19.2% (n=19). The most common perioperative complications were ocular hypertension (OHT, 20.2%, n=20), and cystoid macular edema (CME, 15.2%, n=15). The rate of IOL dislocation was 7% (n=7). Conclusion This knotless technique avoids the risks of haptics fixation but is more prone to IOL dislocation in cases of suture deterioration. Past ophthalmic history needs to be carefully considered in candidates who underwent SFIOL implantation.

Abstract
Purpose: Postoperative hydrophilic intraocular lens opacification can lead to decreased vision and may require intraocular lens exchange. This study aims to identify the incidence of scleral-fixated Akreos AO60’s (Bausch + Lomb) lens opacification and risk factors for this phenomenon. Methods: This is a retrospective case series of all patients who underwent scleral-fixated Akreos AO60 lens at our institution between January 1, 2015 and December 31, 2019. The following data were recorded: age, sex, medical history, indication for Akreos AO60 implantation, laterality, ocular history, previous ocular surgical procedures, subsequent intraocular surgical procedures after the Akreos implantation, lens opacification, visual significance of opacification, and Akreos explantation. Intraoperative and postoperative complications were recorded. Main outcome measures were the overall incidence of Akreos lens opacification as well as the incidence of these eyes undergoing subsequent intraocular surgery. Results: A total of 262 eyes of 257 patients underwent Akreos lens implantation. Overall, 2% (5 of 262) developed lens opacification. Two patients had Descemet stripping automated endothelial keratoplasty (DSAEK) concurrently with Akreos implantation. One patient underwent subsequent Baerveldt glaucoma implantation and DSAEK. The fourth patient had vitrectomy with sulfur hexafluoride gas followed by DSAEK. This represents a 25% (4 of 16) opacification rate among all patients who underwent DSAEK ( P ≤ .01, Fisher exact test). One patient developed opacification after undergoing 2 vitrectomies for retinal detachment in the absence of DSAEK. Conclusions: Akreos lens opacification can be visually significant and may occur after a retinal or corneal procedure that involves the use of intraocular gas or air.

Abstract
BACKGROUND/PURPOSE We report the first two cases of postoperative opacification of scleral-sutured Akreos AO60 intraocular lens after vitrectomy with the gas tamponade. METHODS Two patients with ectopia lentis underwent pars plana vitrectomy, pars plana lensectomy, and scleral fixation of an Akreos AO60 intraocular lens with Gore-Tex suture. Retinal breaks were noted during vitrectomy and consequently intravitreal gas tamponade was used after endolaser retinopexy. Postoperatively, both patients developed intraocular lens opacification but maintained excellent visual acuity; however, one patient developed bothersome though tolerable photophobia. CONCLUSION Although still an excellent option for the management of surgical aphakia in the absence of capsular support, caution should be taken when using a hydrophilic secondary intraocular lens, such as Akreos AO60, during vitreoretinal surgery if gas is required.

Abstract
PURPOSE To report refractive outcomes of scleral-fixated intraocular lens (IOL) implantation with Gore-Tex (W.L. Gore & Associates, Newark, DE) suture and combined pars plana vitrectomy and compare predicted refractive outcomes among 5 IOL power calculation formulas. DESIGN Retrospective case series. PARTICIPANTS Patients undergoing scleral-fixated IOL implantation with Gore-Tex suture at our institution between January 2015 and June 2018. METHODS Comparison of preoperative biometrics with postoperative refraction and calculation of predicted refractive outcome with 5 different IOL formulas. MAIN OUTCOME MEASURES Prediction error and absolute error to compare postoperative refraction with refraction predicted by lens power calculation formulas. RESULTS Thirty-one eyes of 31 patients were included. All power calculations assumed in-the-bag position of the IOL. The Akreos A060 (Bausch & Lomb, Rochester, NY) was implanted in 23 eyes and the CZ70BD (Alcon, Fort Worth, TX) in 8 eyes, and all lenses were sutured 3 mm behind the limbus. Average postoperative spherical equivalent (SE) was -0.79±0.95 diopters (D). Average prediction error (postoperative SE refraction minus target refraction) was -0.19±0.72 D. Postoperative SE was within 1.0 D of target in 25 of 31 patients (81%) and 2.0 D of target in 31 of 31 patients (100%). The repeated-measures analysis of variance of absolute error by lens power formula was significant (P = 0.012), with Haigis demonstrating greater error. There was no significant difference among Barrett II, Sanders-Retzlaff-Kraff theoretical (SRK/T), Holladay 2, or Hoffer Q. CONCLUSIONS For eyes undergoing pars plana vitrectomy with scleral-sutured IOL implantation, assumption of in-the-bag IOL position when calculating lens power leads to acceptable refractive outcomes. Barrett II, SRK/T, Holladay 2, and Hoffer Q formulas were noninferior to each other.

Abstract
We report localized opacification of a sclera-fixated Akreos® hydrophilic acrylic intraocular lens after successful repair of rhegmatogenous retinal detachment with silicone oil tamponade in a nondiabetic patient. No intraoperative lens opacification during air-fluid exchange or lens dislocation was encountered. Granular opacities within the optic were noted at 5 months after surgery, and did not relent to scrubbing with a vitrector during oil removal. Akreos lens opacification under silicone oil is not well documented in the literature. Surgeons must be aware of this potential complication, which is known to occur with various types of hydrophilic acrylic lenses after exposure to air or gas.

Abstract
PURPOSE Explanted hydrophilic intraocular lenses (IOLs) with clinically significant opacification after pars plana vitrectomy (PPV) were assessed for material change and optical quality, in an in vitro laboratory study. DESIGN Retrospective observational case series. METHODS Ten opacified IOLs after PPV with intraocular gas injection were analyzed in a laboratory setting. Analyses included evaluation of patients' medical history, optical quality assessment, light microscopy, histologic staining, scanning electron microscopy, and energy dispersive x-ray spectroscopy. RESULTS In all 10 IOLs a thin layer of calcium phosphate that had accumulated underneath either the anterior or posterior optical surface in a central circular area of the IOL optic caused the opacification. The calcifications lead to deterioration of the modulation transfer function (MTF) across all spatial frequencies. CONCLUSION PPV with instillation of gas into a pseudophakic eye with an acrylic hydrophilic lens seems to increase the risk for secondary calcification irrespective of the manufacturer. In these cases, IOL exchange is the only treatment option available. Since IOL exchange is associated with a high intraoperative complication rate, our results suggest to consider the risk of IOL calcification when implanting hydrophilic acrylic IOLs.

Abstract
PURPOSE Anterior surface calcification of a hydrophilic acrylic intraocular lens (IOL) associated with iatrogenic exposure of air after an uncomplicated pars plana vitrectomy is described. METHODS The clinical and histochemical findings of a patient who developed postoperative opacification of a hydrophilic acrylic intraocular lens are retrospectively reviewed. RESULTS A 63-year-old woman developed fine granular opacifications on the anterior surface of the intraocular lens 8 months after a pars plana vitrectomy with iatrogenic exposure of air. The intraocular lens was explanted and histochemical analysis confirmed the presence of calcium. CONCLUSION Physicians should be aware of this complication and be cautious about the use of intraocular gas in either the front or the back of the eye in patients with hydrophilic acrylic intraocular lenses.

Abstract
Intraocular lens (IOL) opacification is rare but may occur after non-Descemet stripping automated endothelial keratoplasty (n-DSAEK) or intravitreal air injection after pars plana vitrectomy (PPV). We reported two cases of IOL opacification within the pupillary region. Chart was retrospectively reviewed. The predisposing factors and the visual acuity were analyzed. The opacification was evaluated by anterior segment optical coherence tomography (AS-OCT). A 68-year-old healthy woman with pseudophakic bullous keratopathy underwent uneventful n-DSAEK in the right eye. Postoperative vision was 20/40. Nine months after surgery, fine granular deposits were seen in the anterior surface of IOL. The vision decreased to 20/50 but remained stable during 3-year follow-up. A 61-year-old man with diabetes mellitus received PPV and silicone oil tamponade for retinal detachment and vitreal hemorrhage after cataract surgery in the right eye. Removal of silicone oil and intravitreal air injection was performed, and postoperative vision was 20/100. Granular deposits were observed in hydrophobic acrylic IOL 1 month after surgery. The visual acuity decreased to 20/120. AS-OCT revealed hyperreflective materials in the anterior surface of IOL in both cases. An uncommon phenomenon of IOL opacification in the pupil region may occur after n-DSAEK or PPV, which may be associated with intraocular air injection or systemic diseases.

Abstract
BACKGROUND Intraoperative IOLs clouding of several kinds of hydrophilic acrylic intraocular lenses (IOLs) have been reported due to temperature changes. This phenomenon reported previously occurred in cold countries and during the winter months. However, no clinical case was reported about trifocal IOL opacification during operation. We report a case in which acute opacification of the optical region occurred simultaneously when AT LISA tri 839mp(Carl Zeiss) was implanted into the eye. CASE PRESENTATION A 79-year-old woman with a cortex and nucleus cataract was scheduled to undergo right eye phacoemulsification assisted by femtosecond technique. The trifocal lens (AT LISA tri 839mp), which is made of hydrophilic acrylic (25%) with hydrophobic surface properties, was chosen for implantation. As the IOL was implanted into the eye, it became cloudy immediately. Then it was replaced by another AT LISA tri 839mp, which was transferred from lens company outside, the same phenomenon was observed. These two lenses underwent the same temperature fluctuation from cold outside to operating room. Finally, a ZCB00 (Allergan) was implanted. CONCLUSIONS The acute intraoperative clouding of trifocal lens(AT LISA tri 839mp) results from fluctuation of temperature should be noticed.

Abstract
Intraocular lenses (IOLs) can have inadequate support for placement in the capsular bag as a result of ocular trauma, metabolic or inherited conditions such as Marfan's syndrome or pseudoexfoliation, or complicated cataract surgery. Surgical options for patients with inadequate capsular support include alternative placement in the anterior chamber (ACIOLs), fixation to the iris, or fixation to the sclera. The surgical techniques for each of these approaches have improved considerably over the last several decades resulting in improved visual and ocular outcomes. If no capsular or iris support exists, the surgeon can fixate an IOL to the sclera or the patient can remain aphakic. IOLs can be fixated to the sclera using sutures or by tunneling the IOL haptics into the sclera without sutures. This review summarizes the pre-operative considerations, surgical techniques, outcomes, and unique complications associated with implantation of scleral-fixated IOLs.

Abstract
Purpose To compare the development of posterior capsule opacification (PCO) and survival rate without capsulotomy after implantation of a hydrophobic or hydrophilic acrylic intraocular lens (IOL) at the 9-year postoperative follow-up. Methods One of 3 experienced cataract surgeons performed standard phacoemulsification in one eye of 120 patients with cataract. The patients were randomized to implantation of either a hydrophobic acrylic IOL or a hydrophilic acrylic IOL. Both IOLs had sharp posterior edges. Retroillumination images of PCO were obtained with a fundus camera 9 years postoperatively and analyzed semiobjectively using POCOman computer software. Results Seventy-eight of the 120 patients completed the 9-year follow-up examination. Patients implanted with the hydrophilic IOL had significantly (p<0.001) more and denser PCO. The survival rate without Nd:YAG capsulotomy was significantly higher (p<0.001) in eyes with the hydrophobic IOL. Conclusions After 9 years, more and denser PCO developed in eyes with the hydrophilic IOL than the hydrophobic IOL. The survival rate without the need for capsulotomy was higher in eyes with the hydrophobic IOL.
