Abstract
PURPOSE To evaluate the long-term difference in lens epithelial cell (LEC) outgrowth on the anterior surface of a hydrogel intraocular lens (IOL) after curettage of the entire or one half of the circumference of the anterior capsule. SETTING Department of Ophthalmology, University of Vienna, Austria. METHODS Forty eyes with senile cataract only were randomly assigned to Group A, which had curettage of the entire anterior capsule, or Group B, which had curettage of the nasal half of the anterior capsule. Rentsch capsule curettes (Geuder) were used, a straight one for the nasal half and a bent model for the temporal half. One surgeon performed all standardized procedures with a temporal clear corneal incision, phacoemulsification, and in-the-bag implantation of a hydrogel IOL. Two years after surgery, the anterior surface of the IOL was examined by specular microscopy in a double-blinded fashion, and LEC outgrowth was graded semiquantitatively. Anterior capsule opacification (ACO) was also graded semiquantitatively. RESULTS In Group A, grade 2 ACO was observed in 53% of patients and grade 1 ACO in 47%. Similar results were achieved in Group B (59% and 41%, respectively). Two years after IOL implantation, the typically circumferential monolayer outgrowth of LECs on the hydrogel IOL surface was present in 80% in Group A and 60% in Group B. The ongrowth was less dense in the other IOLs; however, no significant differences between the groups were observed. CONCLUSIONS Mechanical removal of residual LECs with a Rentsch capsule curette from the entire or from one half of the anterior capsule did not reduce LEC outgrowth 2 years after IOL implantation. Furthermore, the ACO grade was not significantly different. Lens epithelial cell proliferation in the germinative region and consecutive migration might be the cause of this outgrowth.

Abstract
This study was performed to test viscoelastic artificial tears (VAT) based on both subjective and clinical parameters in patients with keratoconjunctivitis sicca (KCS). Twenty-eight patients were evaluated in a randomized double-blind study. Sodium hyaluronate was used in two different concentrations (0.4%, 0.25%) and in combination with chondroitin sulfate. Each preparation was used for one week preceded by another weekly cycle using a sodium chloride solution. Before and after each cycle, clinical examinations were performed: tear film break-up time, Schirmer's test, lipid-layer thickness and fluorescein staining. Patients kept a record of the drop-frequency, subjective response and side effects. After the study, they were asked to give a rating of the various preparations. The severity of KCS was expressed based on a sicca score and correlated with response to viscoelastic treatment. Both the subjective and the clinical parameters revealed no statistically significant differences between the various viscoelastic agents or between the viscoelastics and the sodium chloride solutions. Severe side effects did not occur. There was a positive correlation of response to viscoelastic treatment with severe KCS (+ 0.36) but not with mild KCS (-0.07). The VAT seems to be indicated in severe cases of dry-eye syndrome. Sodium chloride solutions may be a useful short-term alternative to other tear formulations.

Abstract
PURPOSE To compare the clinical performance of 2 foldable intraocular lenses (IOLs) with sharp optic edges in terms of uveal and capsular biocompatibility. SETTING Department of Ophthalmology, University Hospital of Vienna, Vienna, Austria. METHODS Fifty eyes scheduled for cataract surgery were included in this comparative study. A standardized surgical protocol was used, and all operations were performed by 1 experienced surgeon. Two posterior chamber lens types of similar design with a 6.0 mm sharp-edged optic and poly(methyl methacrylate) haptics were used. Twenty-five eyes received an AcrySof acrylic IOL (Alcon), and 25 eyes received a CeeOn 911A silicone IOL (Pharmacia). Relevant data were collected at a 3-year follow-up examination. To evaluate uveal biocompatibility, anterior chamber laser flare and cell measurements and inflammatory cell reactions were monitored. Cellular biocompatibility was investigated by examining anterior capsule opacification (ACO), posterior capsule opacification (PCO), and lens epithelial cell (LEC) ongrowth on the IOL's anterior surface. Factors such as intralenticular glistenings and IOL decentration were also evaluated. RESULTS Anterior chamber flare and cells and the inflammatory cell reaction were significantly lower in the CeeOn 911A group. There was no statistically significant difference in ACO, PCO, and LEC ongrowth between the 2 groups. The AcrySof lenses showed significantly better centration and a higher density of intralenticular glistening. CONCLUSIONS The findings show that a sharp-edged optic design is, to date, the most effective method of reducing the rate of PCO. Despite a subclinical foreign-body reaction in the AcrySof group, both lenses had a high degree of capsular and uveal biocompatibility.

Abstract
PURPOSE To evaluate the influence on postoperative inflammation of lens epithelial cell (LEC) removal after phacoemulsification. SETTING Department of Ophthalmology, University of Vienna, Vienna, Austria. METHODS This randomized prospective single-surgeon study comprised 60 patients with senile cataract only. After a temporal clear corneal incision was made and phacoemulsification performed, no LECs were removed in Group A, LECs in the nasal half were removed in Group B, and LECs were removed from the entire anterior capsule in Group C. The LECs were removed with a Rentsch capsule curette (Geuder). In all eyes, a foldable hydrogel intraocular lens (Hydroview, Bausch & Lomb) was implanted. Anterior chamber flare was evaluated through dilated pupils in a double-masked fashion using a Kowa FC-1000 laser flare-cell meter (LFCM). Measurements were done preoperatively as well as 1, 3, 7, 14, and 28 days and 3, 6, 12, and 24 months postoperatively. RESULTS In all 3 groups, the flare and cell values increased on the first postoperative day followed by a successive decrease thereafter. One month after surgery, the blood-aqueous barrier (BAB) was nearly restored in all groups. Between the first and fourth week, the flare values in Groups B and C were slightly lower than in Group A; however, mean flare and cell values among groups were not statistically significantly different at any measurement. CONCLUSION The removal of LECs from the anterior capsule with a Rentsch curette did not influence postoperative BAB changes detected using an LFCM.

Abstract
PURPOSE To compare the outgrowth of lens epithelial cells (LECs) on 3 types of intraocular lenses (IOLs) to determine the influence of lens material and lens design (optic edge) on this phenomenon. SETTING Department of Ophthalmology, University of Vienna, Medical School, Vienna, Austria. METHOD Ninety eyes scheduled for cataract surgery were included in a prospective comparative study. A standardized surgical procedure was performed by 1 experienced surgeon. Patients received 1 of 3 types of posterior chamber IOLs of similar design with a 6.0 mm optic and poly(methyl methacrylate) haptic: AcrySof (Alcon), HydroView (Bausch & Lomb), or Sensar (Allergan). Each IOL type was implanted in 30 eyes. Postoperative biomicroscopic examinations were performed 1, 3, 7, 30, 90, and 180 days and 1 year after surgery. Lens epithelial cells in each quadrant of the anterior lens surface were subjectively graded. The product with the highest density and the number of quadrants with this density were used to measure LEC outgrowth. RESULTS Statistically significant differences (P <.05) were seen between the hydrophilic IOL and the 2 hydrophobic lenses from day 30 until the final examination. The HydroView lens had a higher number of LECs on its anterior surface than the AcrySof or Sensar IOL. There were no statistically significant differences between the 2 acrylic IOLs at any measurement. CONCLUSION The findings suggest that lens surface properties have a greater influence on LEC outgrowth than lens design (ie, sharp optic edge).

Abstract
BACKGROUND The treatment of pterygia often results in irregular astigmatism. Corneal smoothing at the end of surgery plays a major role in the development of astigmatism. The aim of our study was to compare the efficiency of corneal smoothing performed by phototherapeutic keratectomy compared with the conventional method performed by a diamond fraise. The effect of postoperative excimer laser smoothing on refraction, visual acuity and irregular astigmatism was investigated. PATIENTS AND METHODS 32 eyes underwent pterygium excision using a standardized surgical procedure. In addition 9 eyes underwent postoperative phototherapeutic keratectomy of the wound region with an excimer laser, 23 eyes were treated with a diamond fraise for corneal smoothing. The postoperative examination was performed 7, 14 and 30 days after surgery. Corneal topography was performed by a computer-assisted videokeratoscope (TMS-1). The results were evaluated by the Fourier transform analysis. RESULTS Both methods showed similar results concerning refraction and visual acuity postoperatively. Preoperatively all patients had an irregular flattening of the corneal topography in the area of the pterygium. Postoperatively a small irregular flattening was left in eyes treated with a diamond fraise. In the excimer laser treated group a steepening in the corneal topography could be observed. CONCLUSIONS The phototherapeutic keratectomy with excimer laser in the treatment of pterygia suggests to be a gentle alternative creating a smooth wound surface. Despite of this advantage the treatment with the excimer laser effects a remarkable increase in administration and expense.

Abstract
PURPOSE To assess the cellular reaction on the anterior surface of 4 types of foldable intraocular lenses (IOLs). SETTING Department of Ophthalmology, University Hospital of Vienna, Vienna, Austria. METHODS One hundred eyes scheduled for cataract surgery were prospectively randomized into 4 groups of 25 eyes each using random number tables. Group 1 received a Hydroview IOL (Bausch & Lomb), Group 2 an AcrySof IOL (Alcon), Group 3 a MemoryLens IOL (ORC), and Group 4 a CeeOn 920 IOL (Pharmacia). Patients were examined 1, 3, 7, 30, 90, and 180 days postoperatively. Postoperative biomicroscopic examinations were done with a slitlamp, and a specular microscope was used to document the presence of cell deposits and identify areas with the highest density of cells. RESULTS The local tissue response revealed 2 patterns: a nonspecific foreign-body reaction to the IOL (small round, fibroblast-like, epithelioid, and giant cells) and a lens epithelial cell (LEC) reaction. The highest incidence of LECs was in the Hydroview group, in which LECs were present on 81.8% of lenses 180 days postoperatively. During the first postoperative days, small round and fibroblast-like cells were found on all IOLs. From 7 days on, the incidence and density of these cells were less severe in the Hydroview and CeeOn 920 groups. After several weeks, epithelioid cells and foreign-body giant cells were seen on some IOLs. These cells appeared more often on AcrySof, MemoryLens, and CeeOn IOLs. CONCLUSION This study found IOL-related differences in cellular reaction after cataract surgery. The incidence of a nonspecific foreign-body reaction to 4 IOLs is consistent with the results of previous studies. The incidence of LECs was highest in the Hydroview group and lowest in the AcrySof group. The CeeOn 920 group had the lowest incidence of all types of cells.

Abstract
BACKGROUND The early postoperative inflammation after cataract surgery is mainly caused by surgical trauma. PATIENTS AND METHODS 450 data-sheets of patients, who were operated for senile cataract with small-incision phacoemulsification and in-the-bag implantation of a foldable intraocular lens were retrospectively analysed. Postoperative inflammation was evaluated with the Laser Flare-Cell Meter Kowa FC-1000 on day 1, 3, 7 and 28. All the operations were done with the same phacomachine model Orbit Oertli. The absolute phacotime was measured, the data classified in steps of 20 seconds. Statistical analysis was made with the student's t-test. RESULTS In the first postoperative week there is a statistical significant difference in the flare-values between the groups with short phacotime (up to 39 seconds) and the group with long phacotimes (over 80 seconds). One month after operation this significance was absent. CONCLUSIONS The early postoperative inflammation is influenced by the duration of phacoemulsification. Surgical techniques and phacomachines that may reduce phacotime are helpful with respect to early postoperative inflammation.

Abstract
BACKGROUND Patients with pseudoexfoliation syndrome (PEX) are known to have a greater degree of inflammation after cataract surgery when compared to patients with senile cataract in otherwise healthy eyes. We performed a randomised, prospective study to compare the influence of the intra-ocular lens (IOL) material of two different IOLs on the postoperative inflammation of the anterior chamber. PATIENTS AND METHODS 28 eyes of 27 patients with PEX and cataract and 29 eyes of 29 control patients were included in this study. The IOLs used were the hydrophilic, acrylic lens: Bausch&Lomb-Hydroview and the hydrophobic, acrylic Alcon Acrysof MA60 lens. The patients were examined preoperatively as well as on day 1, 3, 7 and 1, 3, and 6 months after surgery using the Laser flare-cell meter (LFCM) KOWA FC 1000. RESULTS The preoperative flare and cell values were significantly higher in PEX eyes as compared to the control group. The values decreased after about 1 month to reach values comparable to those in the control group. Over the six months period there was no significant difference between the values of both lenses in the PEX group except on the first postoperative day where the flare and cell values were higher in the Acrysof-lens group. When comparing both groups with the Hydroview-lens there was also no significant difference, except on day 7, between the PEX group and the control group up to 6 months after surgery. When comparing both groups with the Acrysof-lens, there was a significant difference between the PEX group and the control group until 1 month after surgery. CONCLUSION Although PEX-eyes had higher flare and cell values up to one month after surgery, we could not determine a significant difference, except on the first postoperative day, between both IOLs. A significant difference was evident between the PEX and control group in eyes with an Acrysof-lens. Using this clinical model, the LFCM highlights only certain aspects of biocompatibility of different lens types.

Abstract
To evaluate the role of optic edge design of 2 silicone intraocular lenses (IOLs) in 2 year clinical results. Department of Ophthalmology, University of Vienna, Medical School, Allgemeines Krankenhaus, Austria. In this comparative clinical study, 50 eyes had phacoemulsification and implantation of a high-refractive 3-piece silicone IOL with sharp optic edges (CeeOn model 911F) (n = 25) or a 3-piece silicone lens with rounded optic edges (CeeOn model 920) (n = 25). Biomicroscopic findings, including those of specular microscopic examination of the anterior lens surface, were documented and the results analyzed. After 2 years, a significant between-group difference in posterior capsule opacification (PCO) but not in anterior capsule alterations was observed. Behind all CeeOn 911F sharp-edge IOLs, the capsule remained clear; in 2 of 23 capsules behind the CeeOn 920 rounded-edge, a neodymium: YAG laser capsulotomy had to be performed for dense central fibrotic PCO. Seven of 21 of the remaining eyes had first-degree central fibrotic PCO, 14 of 23 had peripheral mixed fibrotic and slender Elschnig pearl PCO, and 8 of 23 had second-degree peripheral PCO. Specular microscopic findings did not differ between the 2 groups. No severe IOL decentration occurred in any eye; 25% in the sharp-edge group and 40% in the rounded-edge group had minimal decentration. The silicone IOL with the sharp optic edge design was associated with significantly reduced PCO 2 years postoperatively.

Abstract
PURPOSE To examine the effect of tropicamide on flare intensity under phakic and pseudophakic conditions and to differentiate between the possible mechanisms of action of tropicamide on aqueous flare. SETTING Department of Ophthalmology, Vienna General Hospital, University of Vienna, Vienna, Austria. METHODS In this prospective study, aqueous flare was measured with the laser flare-cell meter in 20 eyes of 20 patients with age-related cataract enrolled for cataract surgery. Measurements were performed before and 30, 90, and 180 minutes after pupil dilation with tropicamide 0.5%. This measurement was performed in the phakic eye on the day before surgery and in the pseudophakic eye on postoperative days 1, 3, 7, and 28. RESULTS After tropicamide instillation, aqueous flare decreased preoperatively and on all postoperative days. There was a continuous flare decrease until 3 hours after instillation, reaching a maximum decrease of about 30%. Pupil diameter reached its maximum after 30 minutes. CONCLUSION Tropicamide significantly decreased aqueous flare, seemingly by pharmacological means, not volumetric changes. The time between drug application and measurement should be kept constant.

Abstract
PURPOSE To determine the long-term function of the blood-aqueous barrier after small-incision cataract surgery with implantation of a foldable intraocular lens. METHODS The blood-aqueous barrier function in 74 eyes of 62 patients who underwent cataract surgery was examined using a laser flare-cell meter. The measurements were performed pre-operatively and post-operatively between 12 and 35 months after surgery. For statistical analysis a linear regression was used. The study was designed as a single cohort study, with comparison of pre- and post-operative values. RESULTS Highly statistically significant differences (p < 0.0001) were found between pre-operative flare values and those measured at the final visit. The linear regression model showed significantly higher flare values post-operatively compared with those measured pre-operatively. Other variables such as incision technique, sex, operation time, phaco time and systemic disease had no influence on this outcome. CONCLUSION The results suggest that there is persistent blood-aqueous barrier dysregulation even several years after cataract surgery.

Abstract
BACKGROUND Conjunctivitis sicca is a chronic disease of the ocular surface. The substitution of tear deficiency with artificial tears is not satisfying in many patients. In a series of patients successfully treated with acupuncture we observed very different effects on each patient. In this study we evaluate the correlation between the effect of acupuncture and the etiology of the dry eyes treated. PATIENTS AND METHODS 102 patients (87 women, 15 men) with dry-eye syndrome have been needed 10 sessions, once per week, for 30 minutes. We recorded causal factors according to the traditional chinese medicine (TCM): external and internal factors. External factors were: toxic, allergic, drug-induced, ocular surface inflammation and infection, contact lens and generally external irritations. Internal factors were disorders of hormones, immune system, psychic, and vitamin-A deficiency. Ophthalmologic observation included the slit-lamp examination, Schirmers test II, break-up time of tear film (BUT) and a drop-frequency protocol--before and 1 week after acupuncture treatment. RESULTS There was a statistically significant difference (p < 0.001) in Schirmers test, BUT and drop frequency between before and after acupuncture. There was no significant difference between internal and external factors, but the effect on external induced sicca was better. The best effect of acupuncture was found in external factors after inflammation and in patients with imbalance of the autonomic nervous system, the least effects in Sjögren Syndrome. The effect was better in younger then in patients over 50 years. CONCLUSION The study demonstrate, according DeLa Fuye that the best effect of acupuncture is seen on functionally disorders.

Abstract
The aim of this study was to determine the penetration of intravenously administered meropenem into the human aqueous humor and vitreous. Thirty patients about to undergo cataract surgery and fourteen patients about to undergo vitrectomy received a 2 g dose of meropenem before surgery. Specimens of aqueous humor or vitreous and blood were obtained intraoperatively and analyzed by high performance liquid chromatography (HPLC). The study was designed as a non-randomized prospective trial. Thirty min to 12 hr after administration, mean aqueous humor levels of 13.4 and 1.1 mg/l and vitreous levels between 8.94 and 1.08 mg/l were found, respectively. The peak concentrations are distinctly above the in vitro measured minimum inhibitory concentration of meropenem for 90% (MIC90) of almost all relevant gram-positive and gram-negative organisms, including Pseudomonas aeruginosa and Enterobacteriaceae. With regard to its broad spectrum, high antibacterial activity, and good penetration into ocular fluids, meropenem seems to be an alternative to currently used systemic drugs. Its usefulness in perioperative prophylaxis, as initial therapy after perforating or penetrating injuries, or in the therapy of bacterial endophthalmitis has yet to be proved.

Abstract
PURPOSE To compare the course of postoperative inflammation after small incision cataract surgery with implantation of 4 types of foldable intraocular lenses (IOLs). SETTING Department of Ophthalmology, University Hospital of Vienna, Austria. METHODS One hundred twenty eyes were prospectively randomized to receive a foldable silicone (Pharmacia 920), hydrogel (Bausch & Lomb Hydroview), methyl methacrylate/hydroxyethyl methacrylate (Mentor MemoryLens), or acrylic (Alcon AcrySof) IOL. All surgery was performed by the same experienced surgeon using a standardized surgical protocol: clear corneal incision, capsulorhexis, phacoemulsification, and in-the-bag implantation of the IOL. All patients received standardized postoperative medication and follow-up. Postoperative inflammation was evaluated by measuring aqueous flare preoperatively and 1, 3, 7, 14, 28, 90, and 180 days after surgery using the Kowa 1000 laser flare-cell meter. RESULTS Except on the first day after surgery, when the AcrySof group had higher flare values than the other groups (P = .0265), no significant differences were found up to 6 months. Re-establishment of the blood-aqueous barrier was similar in eyes with the AcrySof, Hydroview, and MemoryLens IOLs; the course of postoperative inflammation was different in eyes with the silicone IOL. CONCLUSION Comparison of postoperative flare values after implantation of 4 foldable IOLs showed no clinically relevant differences in the course of postoperative inflammation.

Abstract
PURPOSE To evaluate the effect of cooled intraocular irrigating solution during phacoemulsification on postoperative blood-aqueous barrier (BAB) disturbance. SETTING Department of Ophthalmology, University of Vienna, Austria. METHODS In a prospective, randomized clinical study, 40 eyes with senile cataract had phacoemulsification with irrigating solutions cooled to approximately 10 degrees C (n = 20) or at room temperature (n = 20). Surgical procedure and postoperative therapy were otherwise identical in both groups. Postoperative BAB disturbance was assessed with the laser flare-cell meter on days 1, 3, 7, 14, and 28. RESULTS Anterior chamber flare was significantly lower in the group with cooled irrigating solution on postoperative day 1. There was no significant between-group difference in flare on any other postoperative day. CONCLUSION Cooled intraocular irrigating solution reduced immediate postoperative inflammation compared with irrigating solution at room temperature. However, this effect was of short duration.

Abstract
PURPOSE To evaluate inflammation after clear corneal incision (CCI) cataract surgery in patients with noninsulin-dependent diabetes mellitus and no retinopathy. METHODS Forty patients with diabetes and 40 age-matched controls had standardized temporal CCI cataract surgery with implantation of a foldable intraocular lens. Anterior chamber flare was evaluated in an undilated eye with a laser flare-cell meter preoperatively and 1, 3, 7, 14, and 28 days postoperatively. RESULTS In both groups, flare and cell values increased on the first postoperative day and successively decreased on the following days. Flare had not recovered to preoperative values by day 28. At no time was there a significant mean difference in cell and flare between the 2 groups. CONCLUSION It does not appear necessary to alter the postoperative therapeutic regimen in patients with type 2 diabetes mellitus and no retinopathy.

Abstract
PURPOSE To compare two standard small incision techniques for cataract surgery--clear corneal incision and sclerocorneal incision--with regard to postoperative disturbance of the blood-aqueous barrier (BAB). SETTING Department of Ophthalmology, University of Vienna, Austria. METHODS This prospective comparative study comprised 108 eyes with senile cataract. A clear corneal tunnel incision was made in 53 eyes and a sclerocorneal incision with tunnel preparation in 55. All other surgical procedures and postoperative medication were standardized. Postoperative BAB disruption was measured with a laser flare-cell meter (Kowa FC 1000) in an undilated pupil on 1, 3, 7, 14, 28, 60, and 90 days postoperatively. The values were compared using a two-sided t-test. RESULTS In both groups, flare and cell values were highest on the first postoperative day. They gradually declined but without recovery of preoperative flare values on day 28. At no time was there a noticeable between-group difference in mean cell and flare values except for flare at day 14 (P = .04). CONCLUSION Postoperative trauma, measured by the BAB disturbance, was equally low after clear corneal and sclerocorneal incisions.
